I've bought and sold tons of stuff thru Ebay since I signed up back in '01; graphics cards, posters, car parts, r/c parts, home decor, and on and on. I try to stick with new stuff or used items that don't tend to wear, and try to stay away from the extremely cheap, low quality or knockoff items. I've had one problem, and that was with a new 383 crate engine I bought. Some parts were missing, but turned out it was the shipping company at fault. Other than that, overall good experience. If you're buying, try to stick with sellers with a high positive feedback score.
