I know there is a waste gate model but iv read alot where the VNT setup with the GT20 was used, to reduce the lag... And £300 isn't bad 
for effectively a brand new turbo with upgrades its cheap. But you can always run second hand, reliability will always be a concern though as you don't know its past. At the end of the day he needs to specify what power he's after and where he wants it before people start telling him a definitive turbo to buy. No point fitting a GT20 if your after Sub 150 BHP.
