Cheapest I've seen this so far. The price at the time of posting was €49 (which according to Google is about £42).
UPDATE: I completely forgot about postage. As mentioned in the comments, this comes to about £49 with postage included.
Considering this is brand new, it looks like a better deal than the Tesco 'Refurbished' one for £45. (Update: Not cheaper when you include postage)
I haven't ordered it myself but it is approaching the biting price.
