The more cfm the better! but I doubt if you'll find anything bigger than about 17 cfm which still uses 240 volt power. With 25 to 30 cfm you wont have any problems with lack of air.
There is a place out Mortdale way that has quite a range of compressors. I recently upgraded mine from there and I think the next step up required a 15A power point. Anyway, I'm quite happy with the unit I have now - it does everything I need, die grinder, sand blaster etc. with something to spare. I *think* it is only 12 CFM and has a reasonable sized reciever.
The name of the place is 'National Air Compressors'. Address: Unit 36, 17 Lorraine Street, Peakhurst. Well... 2 out of three is OK!
15cfm compressor will be adequate.
A Star spray gun as Redbus says is a adequate gun for the job. I used one for 10 years, and never put a rebuild kit through it. Very good value for
money.

Hey 14yearold,
As I said before I'm quite happy with the one from National, if the price dosen't worry you - go for it!
