Thanks for the replies but i ended up pulling the trigger on one today.
My father had bought me a 6g pancake, a low budget socket set and impact gun from Rural King.
I ended up taking them back and they had a DeWalt 15g compressor that had been recommissioned that i think will be good for my needs. It was $200 vs. the new one which was $375 so it'll be plenty for what i'll most likely use it for.
I noticed the impact wrench he gave me said it needed about 4.7cfm for good performance. Then i saw at the store the $200 Chicago Pneumatic said it needed 5cfm. So i figured at 5.4cfm this tank should be fine with whatever i decide to get.
