As someone that sells a lot of E-Bay when pricing anything used, figure 60-70% of what NorthernTools.com sells it for in their catalog. A Husky 385 is $830, so used that is $498.00. That is a lot of money to sell something used, sight unseen on E-Bay, with no warranty, and it comes close to the $500 item warranty limit from E-Bay. So, I would start at $400 tops. I would not bother with a reserve, many buyers myself included skip auctions with reserves or hidden bidders.
