Has anybody advised the OP to decide what riding characteristics he wants from the bike before settling upon one? Or is that not the Singletrack way?
Scruff bought a Yeti 575 and couldn't get on with it at all because it wouldn't "pop" off the jumps like he wanted it to, so he went back to a Heckler which didn't soak up the miles the same, but was nice and lively when he wanted it to be.
Another mate of mine has got a Titus Motolite. He loves it for big rocky all-day rides in the mountains because it stops the trail beating him up. But for whizzing round the tight twisty stuff and having a 2 hour blast he chooses the Voodoo every time. However for 24 hr races he goes back to his short travel Rocky Mountain Carve because it behaves like a hardtail but with a bit more give.
You can afford to try quite a few £50 test rides to get the bike that suits you on that budget. Unless you prefer the idea of having a trophy bike, rather than riding it.
Edit – oops, Hicksville said "decide on the ride", and others too may have.
