Defo leaning towards the px bike in the under a 1k bracket and as Andrew sais can slightly modify it in the bargain basement
John- don't know too much about cross bikes but the one i'm after needs to be versatile so i can use it for the winter training etc,thats not saying i havn't done hours of research on the net-part of the fun of it. The only thing is i'm a bit unsure of the sram set up on the px bike as never used it before
