Compressor Size for Paint

What kind of specs should I look for? HP, tank size, all that kind of jazz.

Later

60 gallon 12 cfm atleast.

I bought one from Sams club which I think is a 80 gal and around 15 cfm for around $700 bucks. It was the best deal and fastest cfm that I could find without spending a couple grand.

are you using hvlp or reduced pressure guns?

Im useing a 80 gal 7 HP 24.8 cfm at 175 psi Snap-on one that is made by Big Red Air works great for everything but it cost a bunch.

i have the husky 80g 2 stage (made by campbell hausfield) i got from home depot of all places for about $800.
