if you do decide to go the cheap chinese route, i.e. £170 inc delivery, then do not expect the turbo to last more than a year and do not put it on a tuned car. i fitted a 19t from ebay to a car in the past, was absolutely fine under town driving conditions, can't fault it there, but put any amount of power into it and yes, it will cope, for about three months if used aggressivley. they are not the same build quality of a genuine article, hence why they are so damn cheap. imo of course. i am running a chinese core on my 2.2 9-5 and so far it has been brilliant, 25,000 miles in 6 months, no extra smoke, no loss of boost. i think it all depends on what level you are going to use it.
