The compressor hangs on the terrace wall. Anyone know of a manufacturer?

I am a weekend do-it-yourselfer looking to buy an air compressor to aid in a project basement finishing of a 12’ x 12’ room. One tool I would like to use is a framing nailer with an air compressor to frame the partition walls. I really don’t want to spend a lot of money on a compressor. I have spoken to a tool manufacturer on their framing nailer and they keep saying they recommend an air compressor with 6 CFM @ 90 PSI. Doesn’t CFM mean the recovery rate of the compressor? If I have 90 PSI coming through the regulator then it should work fine right?

If I have to waiting a few minutes between shooting a half a dozen nails, its no big deal.
Would I be better with a 150 max PSI compressor or one that is 125 max PSI?

Compressor?
Porter Cable 150 max PSI, 6 gallon – 2.6 SCFM @ 90 PSI ($180 US, includes brad nailer)
or
Campbell Hausfeld 1.3 H.P. 125 max PSI, 15 gallon – 3.7 SCFM @ 90 PSI ($180 US)

Framing nailer?
Grizzly 21 degree round-head model #H7665 ($100 US)

Thanks!!!
Aussie, you sound like your giving me advice if I were a new contractor. I will only be using nailers …no wrenchs, grinders, or sprayers. I still consider CFM recovery….Is it not true that CFM is the flow of air into the tank that the compressor motor can produce? If so, CFM is only a term used when the compressor is running….when off, you simply have PSI until it lowers to the point that triggers the compressor on to repressurize the tank at the desinated flow rate (CFM). ……maybe I am wrong, but this seems to be logical. As I stated before, I have no problem waiting after every 1/2 dozen nails for the compressor to catch up. I’d rather do that than pay an arm and leg for one you suggest

it came in a combo kit with a trio of nail guns… porter-cable combo thing

I’m wondering if I can just buy an air sprayer for paint and hook it up to that – is that adequate psi for paint application? the thing does have an adjustable psi bladder or whatever but i’m wondering if the power cycling of the pancake type compressor will wonk up the even-ness of paint application
?
thanks~!
after reading the first response (which is appreciated) let me also add – this sprayer would be used for doing a rather small job at a time – spraying a built-in cabinet i’m adding, for instance

this won’t be used for any LARGE surface at any given time – just for some you know, interior latex type paint application on, say, 6 sq ft surface max
