Turbos on eBay

Hey guys,i noticed that some of the turbo kits on ebay are really cheap.seems to me that,how can you buy a kit that has:turbo,ss exhaust,downpipe & a couple of other pieces for $600?
has anyone had any experiences with any of these kits.i notice that a co. called SSAutoChrome seems to have these kits for sale on a regular basis.Any insights into this?

well check his feedback and see what people say about his turbo...most of these ebay sellers sell garrett t3/t4 turbos and i heard those aren't bad so yeah

got a link for us?

yeah,the address is:ssautochrome.com

You take a gamble when you buy off eBay.
