OK guys, starting to look @ air compressors and nailers . Will be doing some walls in my workshop soon and decided to finally treat myself to a framing nailer as well as later (what I really need ) a brad nailer. Of course, need an air compressor. Realizing I'm a hobbyist and with a bad back ,(don't want a 200lb monster), what should I look for and what really matters? Is CFM the key ? how about HP, tank size and PSI? Should I get oil-less or direct drive or belt drive? What brands do you guys reco? AND what nailers are the best and what sizes should I get for WWing? Do u need a finish nailer if you have a brad nailer? Anyway, you help/ advice will be a big help!! This post shows how little I know about this subject. For years, I have resisted because I dreaded the idea of dragging around the compressor and the wire. Thanks in advance...
