Here is some tips about
ebay in general.
Always check feedback. If the seller has little or no negative feedback and many sales, you shouldn't have a problem. It is harder to tell with smaller sellers with maybe 100 sales instead of 1000.
Be wary of sellers with more than a couple negatvie feedback ratings, even if they have a 99.9% positive feedback score. The higher number of negative feedback left for a seller typically means that they were doing something wrong.
That said, be sure to find the comments left by those who left the seller negative feedback. Often someone will complain about something that's a bit ridiculous, and at other times they may say "broken product" and the seller will reply and say "please contact me for a return." You can usually tell the demeanor of the seller this way.
Also count mutually withdrawn feedback as negative feedback as well. A lot of sellers will leave you negative feedback if you leave them negative feedback and then offer to mutually withdraw it. A famous seller for doing that is sadly one of ebays richest self-made millionares who sells used and often DOA, generic brand hard drives in a homemade enclosure, markets them as western digital or maxtor under the name narro (

Know the price of the item you are buying. If you are buying something that everyone else is selling the same item in the same condition etc for twice as much or more, it might be a fake or a scam.
Finally, here is a rule to never break. NEVER buy anything from China under any circrumstances. In China, it is legal to counterfeit and I am seeing more and more Chinese fakes every passing day on
ebay.
If you do what I said, you should never have a bad
ebay transaction. I know from experience //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
