RE: Buying a plane on ebay...
Warranties may not be a problem, but it is not something to be ignored either. Some of the Ebay sellers are brick and mortar stores that use the volume of Ebay to get better terms from their suppliers. Buying from an individual though is a different story and you need to check their feedback closely, especially ones with a low number of feedbacks. Most individuals will state "as is" in the add, or at least imply it on used stuff. I guess botom line is that if you don't feel compleetly comfortable with the terms, comunications, or shipping, skip it. Saving $10 or $20 bucks maybe, isn't worth the possible headaches if you are not comfortable with what you see. Like anything you are buying sight unseen, If you can't afford to take a bath on the purchase, don't bid on it.
