A frame to be added to the above list in the sub £300 bit, is the new BT raven, very short 382mm chainstays (shorter than a koxx) very long 1090mm wheelbase, it is more designed towards the "proper" uci style of riding, it has a 5mm rise BB, also availiable in black, white or silver and it rides amazing, better imo than any other frame, be it more or less money, except maybe an echo 1080m pure, but I haven't ridden one so can't compare.
