I generally sell stuff on ebay but don't often buy. I've had some really good luck and some really bad. Beware of refurbished items and auctions where the person says that they don't accept returns. Make sure to look at the feedback of the person selling the item. You can click on the number beside their feedback percentage to see the actual negative feedback if there is any. That will allow you to see why they aren't 100% if they aren't. Use a verified paypal account if you can because it does protect you a little more against evil people. I'm not trying to scare you away from the idea at all... I'm just pointing out that like everything on the interwebs caution is recommended.

Yea...i understand what you mean...but i have a question about the feedback!
Evil people can't put their friends to do positive feedback?

Oh of course they can. Sometimes people will boost their feedback by buying a whole bunch of really cheap items. Make sure to look at their "Feedback as seller". Most people will have a bit of history. Don't get attached to one item if you have any doubts. There are tons of duplicates for most things.
