Air compressor help

One of my air compressors is a Husky (Home Depot) and IIRC delivers 5. something scfm @ 90 psi and has a 33 gallon tank.

It will run a air ratchet, 1/2" drive impact gun or diegrinder. It won't run an airfile or oribital sander for any period of time. The die grinder will just about kill it too if run it for any length of time (more than 5 minutes).

I now have a bad *** 220v 5 hp continuos duty rated electric motor with a big *** cast iron twin cylinder compressor head and 75 gallon tank. If the tank is at zero psi, I switch it on, walk out for a smoke I'm at 100 psi. I love this thing.

I guess what I'm getting at is save up for the best you can afford as you can never have too much air.
