I sent my turbo for reconditioning as the seals had gone and bearings were worn. I was quoted £100 over the phone but when they got it and stripped it they said it needed loads doing and it would cost £360, about the price of an off the shelf refurb. I got another one off interweb with no play in shaft and no oil leak for £60. Works a treat. Depends how much you trust your own judgement I suppose.
