I've been with Ebay since 2001 and have had great success with buying things from kits, parts, tires/wheels, engines, etc. The most important thing you need to watch out for; like others have said is, their feedback rating. Ebay is where the great deals and bargains can be had if your patient and do your homework. For example: I purchase a NIB Ninja JX .21 $240, OS Speed II $385 and tons of other stuff for well below even LHS prices. I like to support my LHS, but my money has to go to where the best prices are at.
