I picked one of these up from Aintree PC World today - they still had 1 left.
Manchester Chester road have 5 in stock this morning, and Llandudno had stock also..
Not checked anywhere else.
Presumably reduced due to the new one coming out, but in my opinion this version is better, especially if you use patch stick and add XBMC and Boxee etc...
EDIT : this also seems to be available to order via telephone if you quote product code 168218
