It will give you a good idea of what to look for in a compressor.
I wouldn't buy a 200psi compressor period. I would look for a compressor that would put out 10+ cfm at 90psi. I have a Campbell Hausfeld 6HP 60gallon. You can get tham fro around $400-$500 at HD. You will need a 220V outlet with at least 20A to run it though.
Good luck,
Chris
