I am going to be buying an air compressor and tools, and need some advice in this area. How big of a compressor should I get, any particular brands to avoid? What I plan on using it for is an impact "gun" for lugnuts and stubborn bolts. What do compressors run on, gas? Everything for me up to this point has been hand tools, so I am new to pneumatic tools. Are air ratchets worth there price and again, any advice on brands?
