This is the best price i've seen this at, it's on a this week only deal on Overclockers UK at the moment.
A good deal for people who have been registered on their forums for a while (and get free delivery). Or pick it up in store if your near Newcastle-Under-Lyme.
For those not eligible for free delivery it'll cost about £3-£4 more and is probably not for you (ebuyer is doing this for £49 iirc).
EDIT - Now out of stock on eBuyer & £57.99 on Amazon.
