what AM frame?

skinheadjc

I'm going to be selling the turner rail pretty soon as 4x is just not the sort of riding i do anymore, so i'm gonna be looking for an AM frame in the next few weeks, will have to be either less than £600 new or 2nd hand.
So what should i get / look out for?
Forks will be mazzochi all mountain 1 sl's buy the way and most of the bit will come from the turner.
