nickwild6, if you're talking about waku7 (i think the name of their business is New York Game Console) they are top-notch. I've bought refurbishment services from them for DSL and bought refurbished consoles from them. Really fast service (at least for DSL). It made me think they just replaced my unit and kept the parts from my old one.
They also handled a special request by email for a small charge (I wanted a special, brand-new housing on my refurb DSL which I had sent in for having a bad Slot 1).
