Honda FTW. But I agree, expensive.
I bought a Champion 2000watt gen for running an air compressor in my quad trailer. Had it for 4 years, about 200 hours on it. Runs awesome. Never had a problem with it. Works hard, runs fairly quiet and has plenty of juice. Cheap too, under $500. It even has an economy mode that lowers the idle for simple things like lights and chargers.
