Oil or oil-free air compressor

Once I bought an oiled compressor, I will never go back to oil-free unless it's a small pancake style and I have no choice. Oil-free compressors don't last as long and are annoyingly loud. The compressor is often times the heart of your shop, so don't skimp and do it right the first time. I have always had US made Campbell-Hausfeld compressors, but I got lucky and scored a great deal on a Quincy QT-7.5. It's hands down the best compressor I've ever owned.
