I'll throw in my opinion but I may not be using my equipment right...
I personally like the small gravity one I've been using in a blast booth over the harbor freight pressure one. The pressure one just blew way way too much sand out too fast. It felt dangerous and uncontrollable. The gravity fed one seems more controllable. Then again, maybe I'm not using the pressure blaster correctly. Plus, I never tried the pressure blaster in the cabinet. Also, I don't think I'd attempt to do my frame with the gravity fed, either try again with pressure or pay to have it done. So far I've been happy (annoyed at times with humidity) with the gravity for small parts. I'm going to attempt the pressure blaster on my frame this winter when humidity is low; may give up and take it somewhere.
