Badguy Alert!
Sorry to hear about your bad experience. Stories like that just give Ebay a bad name and just adds fuel to the fire. I haven't had a bad dealing yet but wouldn't let one bad experience overshadow the many good ones that I've had.
Hindsight is 20/20 but looking at midsouthauto801's profile, he/she only has a feedback rating of 1. It could very well be his own from another profile. Try to stick with sellers that have at least 20-30 total AND 95+ % feedback ratings.
