I've bought a lot of my stuff from ebay. Its pretty safe if you just check the seller feedback.
I got my Koni's from ebay, my neuspeed braces (used), my factory service manual, and lots of non-car related stuff.
You can find good deals on ebay. I don't buy the worthless crap tons of people post up there, but I have gotten some good deals on quality brand-name stuff :thumbup:
