I should get some air tools. They're awesome, plus it means I can get an air compressor. This is good for tire pressure adjustments etc. What compressor do you recommend, that will run an air ratchet/impact gun without needing to stop and let the tank recharge frequently, and is portable enough I could horse it into the back of my truck for track day duty? The given picture is a compressor, but likely is overkill for my application.
