As far as Ebay is concerned just remember their own warning. Caveat Emptor. Look around locally. Someone at your local field may have an airplane for sale that will fill your needs. At least you will be able to hear the engine run and see the model fly. On Ebay the shipping charges are usually add more to the cost than buying a new model on the internet from Tower, Horizon, Omni, Hobby Lobby or Hobby People. Another advantage to buying locally, if possible, is that you can probably find an instructor at the same field.
