When I bought my house I promised myself I'd buy a good air comprerssor, one that wouldn't have me wanting more. I bought a 6.5hp Craftsman 60-gallon vertical tank, 240V, 14.7cfm @ 90psi, 130psi max. I re-circuit breakered (for lack of a better word) my circuit breaker box and made a dedicated circuit for my compressor. Not one single solitary regret! I love it!! Save yer pennies and get the best unit you can.
I've been using my die grinder with some kind of semi-soft abrasive wheel to take the rust and paint off my 914 -- and finding more and more rust
and shoddy patch repair on the nose/headlight assemblies....mother #$@!ing previous owners
-- and the grinder definitely keeps the compressor cycling.
Tools are spendy! I recommend a tire inflation kit and air blower kit -->

Don't forget to get a clear face shield to protect your eyes and ear muffs. Draining the air from the tank in a garage is NOISY and you don't want to damage your ears
