Can i trust ebay for buying a used PDA?

I wouldn't do it, where is he located is a good question, do they want you to mail cash or are they using paypal. I wouldn't do a transaction over ebay without payal, and ask to see more pictures of the Pda. People who steal pictures don't normally have more. Also sometimes they might have a buysafe thing at the bottom of the page. Idk that much about that though. So just be observant and if you feel it is a scam it probably is. Sometimes it is just best to buy it at the store, even though you want a good deal it may not be the best choice.
