I'll be doing mostly mechanical work with it. Impact wrench, air ratchet and such. Maybe I'll do away with the DA and sprayer requirement until I can justify the added expense. I saw a couple of DAs say they require 16cfm. Is this realistic or can you get away with less without too much waiting for the tank to fill? I mean that's a really serious compressor. I would like to able to use a cutoff wheel here and there and do minimal die grinding. I would like to do some pocket porting. What do you think the real world cfm requirements for them would be. As long as it's not painting I suppose I can live with some interrupting wait time. I can live with $500-$600 but $1200 and up is too pricey for me. I'm working on buying a new house. Again I appreciate everyone’s input. ---Rich
