Air Compressor - need advice and recommendation
I could really use a small electric (110VAC) air compressor for the garage. Would be used primarily for tire inflation (up to approx 90 psi)and maybe for small air tools.
Home Depot, Lowes, Sears and others seem to have some attractive buys (< $150) which look like what I need but the reviews aren't good on some of them. I'm not even going to consider anything from, say, Harbor Freight.
Would appreciate any advice experience, comments... etc. Thanks

I bought a Porter-Cable 150 PSI for about $150. It will NOT run an impact wrench to remove lugnuts. Be sure to spend a little time online reading reviews. I think the reason why my compressor will not run the tool is not because because the PSI isn't high enough, but because there are small lines to the air fittings and it does not provide the volume needed to run the bigger tools.

I did some research about a year ago looking for a good quality, quiet and portable air compressor. Something to use for smaller jobs such as tires, blowing dust, nail guns etc. Ended up with a Makita MAC700 and have no regrets. It is compact, quiet, well built and refills the tank from 100 up to 125PSI in about 15 seconds. I don't recommend this for running larger impact drivers unless you piggy-back an extra 4 gallon or larger receiver tank. With the piggy-back tank you will have the air volume needed for impact driver use. If you have to run larger or multiple pneumatic tools at the same time I would recommend a bigger compressor.

Look for something that has a 20 gallon air tank at a minimum. That size tank will allow for inflating tires, using some air tools like a impact wrench or air ratchet. Tools like air powered drills, sanders, grinders will use up the air in a 20 gallon tank quickly and the motor will run every minute or two. Look for a compressor with a 150psi capacity or even more. Most of the compressors sold at Home Depot or Lowe's are made by Campbell-Hausfeld. That's a good brand with many years experience in homeowner style compressors.
Most of the compressors with that size tank will have direct-drive oil less pumps which can get pretty noisy. Belt-driven pumps will be quieter but that makes the compressor more expensive. There are some compressors that have the tank mounted upright so that means a smaller footprint. Most compressors in the 10-20 gallon range will have wheels so they can be moved to the work.
Compressors in the 20 gallon size will need a 15 amp circuit to work well. Most garages should have a 15A circuit.

Found this air compressor sizing info online and is based on the tools you may want run with it.
Air Compressors for Home Use –
Many homeowners will use smaller, portable air compressors (either hand-carried or wheeled) that move easily from the garage to the house, yard or roof. Common air tools such as brad nailers, reversible drills, and impact wrenches require about 0–5 CFM (Cubic feet per minute — units in which air flow is measured). It's important to know if the compressor you purchase will drive the air tool you'll need for your project. For example, smaller air nailers run on 2 to 5 CFM at 70 to 90 PSI, while larger shears, sanders require up to 10 or more CFM and 100 to 120 PSI.
How do I determine my CFM Requirements?
The chart below includes some common air tools and their average CFM measurements. Reference this chart to determine what continuous CFM rating is required of your air compressor. Air tools are often rated as “Average CFM.” “Average CFM” is typically based on a 25% duty cycle (15 seconds out of a min.). This sometimes creates a problem with tools that are used on a continuous basis (ex. orbital sanders, die grinders, etc). Nailers and impact wrenches typically don't have the same problem since by their nature are used more intermittently.
If you plan on using an air tool on a continuous basis, it is a good idea to multiply the “Average CFM” x 4 to get a continuous CFM rating for the tool.
Air Tool Description-------------Average CFM @ 90 PSI
Angle Disc Grinder - 7"--------------5-8
Brad Nailer-------------------------0.3
Chisel/Hammer---------------------3-11
Cut-Off Tool-----------------------4-10
Drill, Reversible or Straight-Line-----3-6
Dual Sander----------------------11-13
Framing Nailer----------------------2.2
Grease Gun-------------------------4
Hydraulic Riveter--------------------4
Impact Wrench - 3/8"------------2.5-3.5
Impact Wrench - 1/2"--------------4-5
Impact Wrench - 1"----------------10
Mini Die Grinder--------------------4-6
Needle Scaler---------------------8-16
Nibbler-----------------------------4
Orbital Sander---------------------6-9
Ratchet - 1/4"-------------------2.5-3.5
Ratchet - 3/8"-------------------4.5-5
Rotational Sander-----------------8-12.5
Shears---------------------------8-16
Speed Saw------------------------5

I also like this one. The Hitachi EC99S has very similar specs to the Makita MAC700 compressor but also has a larger tank, 4 vs 2.6 gallons. Only thing I would check on is the warranty which I could not find but would expect it to be one year.

You people are amazing! Lots of information to research and digest. The Makita and Hitachi were great suggestions and I also learned that an oil-bath compressor is typically quieter and longer lasting than than one without, hence better value, if more expensive. I had pretty much figured the best deal was outside my budget range, but worth every cent.
As I mulled these ideas over and over, I started to develop this image of the neighbor kids asking if I could blow up their football and then wheeling (wheels optional) out this 20 gallon, 45 lb compressor....
All good stuff, and I may buy that big oil-bath "Binford" (RRRRrrrrrr) style compressor just because of the value and because it looks so cool. Even if I do have to move it everytime I want to get the cars out of the garage.
Thanks to all of you who contributed your valuable advice.
i wonder if I paid just a bit more the guys at E@RTC would allow a space for me to show off my new compressor?
