do what redwing says, and then go to the category....it should be something like "hobbies and crafts: models: airplanes: gas powered"

Redwing is right, there are some lemons out there, and the new engines that I've seen really don't sell for cheaper than you can get them from tower hobbies or someplace similar.....plus you get nailed on shipping charges sometimes....always look into that before you bid.
