I was wanting to get an air compressor for my garage. I don't know much about them so I'd like to hear what others use or have used. What do you like, what don't you like?. And about what did you pay? I wanted something for blowing off equipment, blowing out filters, filling tires. Mostly small jobs. But who knows what I might need it for down the road? Will one of those small "pancake" style units suffice? Or what should I look for in HP, max PSI, and gallons? Thanks in advance!
