I check the auction site every now and again but all the decent ones near me seem to go for crazy prices. I watched one on craigslist not sell for months for what I thought was a reasonable price. It had a little over 5,000 hours on it but the guy was down to $1800 for a running unit with fresh oil, filters, and batteries. It was cleaner looking than mine. He had never load tested it beyond running something on the convenience outlet though. I was going to buy it myself before I snagged the one I have.
