My current gearbox in my S2 ERST is a matter of miles from being completely useless, therefore I'm looking for a replacement.
I've been quoted £300 for a second hand one or £500 for a reconditioned box(not fitted). The car is currently pretty much standard but future plans do include power in access of 200bhp therefore I'm afraid a 2nd hand box will be knackered within months.
I was wondering if anyone can help/advise me.

p.s. I live near Manchester (in case theres anyone locally who could sort it)
