I buy and have had (so far) good experiences. I check it out as much as I can before I do.
Haven't gotten into the sell side of it yet but I'm thinking bout it as there are a load of Motorcycle parts for Bikes long sold hanging about.
Good Luck Uncle Toad..Clinton's right...Guard yourself as you would in any situation. Let the bidding commence..:>)
