Reading from JohnA's experience with AET I will not be taking my business there, has anyone had a good experience from a turbo recon company?

I'll be coming into posession of an old turbo for my punto gt shortly, I'm currently running a T28 with 360 degree thrust bearing and cut back blades, I would like to get the new one reconned and possibly run a roller bearing..

Anyway, can anyone recommend a company?

Is it a simple matter of bolt off bolt on and refill colland and oil?
