Rob,
Send me a PM with your phone info and such. My phone gave up the ghost. As for compressors, I got a bit lucky. A guy about an hour away had rented a warehouse and all he had in it was a compressor, dryer, material cart, office desk, and a CNC lathe. he manufactured fittings for Wagner paint guns. It was a two man show, ran the lathe all day and is set to retire from it! Long story short, after he closed his shop he was looking to get rid of everything he had as quickly as possible so he wouldn't have to pay more rent. I walked out of there with an IR 100 Gallon 7.5hp compressor, IR 115V refrigerated dryer, IR inline filter, Automatic drain valve, all lines, pneumatic vise, material cart, cold rolled material, and lots of little doo-dads (no lathe, of course) for $1000 US. The catch: the compressor is 3 phase. So i built a rotary phase converter for about $500 and now for $1500 I have a bitchin air setup and 3 phase capabilities. Moral of the story is that 3 phase equipment is often much cheaper than single phase and built to used and rotary phase converters are a great value. It may be out of the budget but with the work you do I don't think air is a place to skimp.
