As an adjunct to a companion thread I checked on the latest status of Engine Analyzer. A new version - 3.2 - is out and its major enhancement appears to be an "optimizer" that will iterate various parameters of your choice and may do tens, even hundreds, of thousands of runs to optimize specific components or specifications. This is all well and good - IF you would consider having lots of custom parts made. For the rest of use, whose budget will only support procurement of off-the-shelf commercially available parts, the iterator functions are not terribly useful IMO. I don't need to test 2000 cams to optimize a configuration to my objectives. No price was listed but you can check out version 3.2 at the following link.

Another link was advertising EA 3.0 for $109.50 versus a "list" price of $149.95. (Guess they need to clear out all the 3.0 inventory.) If you're really serious about doing engine system engineering work, I think EA at this price is the way to go over DD2000 for forty bucks. EA is more difficult to use, especially for the novice, but it is more flexible and you will definitely learn a lot if you persevere and learn how to effectively use the program. It's pretty good engine system engineering tool.
