£500 to spend to Replace the Raliegh Montage I sold for £1

mattfefc

I know this is a boring common question.

I've sold my old bike from when I was teen,

I want to get a new one and I've got down to three. What one would you choose or would you decide on a different one. About £500 to spend.

1) Giant XTR 4.5 2008
2) Kona Blast Deluxe 2008
3) GT Avalanche 1.0 disc 2008

Are there any difference between them, any help would be really appreciated

Thanks,
Matt...
