The fees were not really that bad. I ended up posting 7-8 pictures, adding a buy-it-now price, and a bunch of other options. The total was only around $34 dollars. I don't think I would try to sell a boat without pictures and some of the other ebay options though, but I am sure I could have added more expensive sales gimmicks.
The $34 was the listing fee. You'll pay a fee on top of that because it sold.
