I've been buying and selling on ebay for 9 years and have only had three BAD experiences BUT I was covered by using Paypal. I have bought 3 cameras from ebay in the past 5 years and have been very happy, and am now selling a camera on ebay for the first time, so, when this Auction ends and if I end up selling it I will get back to this link and tell you how it went.
My advise, only deal with people who have 99% to 100% feedback and more than 100 feedbacks and only use Paypal for security reasons, and then you shouldn't go wrong.
hope this helps.
