Ok, I'll be nice. You're an idiot. That said, eBay is a pretty big place. There are numerous vendors, products, and qualities of items on there. No one can tell you if the one you're gonna buy will be good, because you have posted nothing relevant or helpful. Anything you buy on eBay can be crap, or it can be good. Just be careful of certain vendors with low ratings and remember that cheaper is not always better. Also, the swing arm is a vital piece of the motorcycle and I would definately NOT cheap out on that because there is always a chance that a weld could crack, and you could get hurt or killed (probably killed because I'm willing to guess that you don't wear much gear).
Find a link and then we can talk.

Rad's in Brandon can help you I believe.
