Ebay Chinese turbos are getting better in quality every year, they are not half bad now. Might be worth getting one to start your build, then replace with name brand if it goes bad. GT35? My wastegate will cost more than my freaking turbo!
Another cool thing about the chinese turbos is that good reputable companies make rebuild guts for them so you get your foot in the door with the cheaper turbo then rebuild it with quality guts down the road.
I have a holset HX35 that could use a rebuild I'd sell cheap.
