If anyone in the UK's after a bargain PRS-350 or PRS-650, then Waterstones have some:
http://www.waterstones.com/waterston...-readers/1918/
Pink or silver PRS-350 @ £89.99
Black or silver PRS-650 @ £129.99
Plus various cases. I'd have got one myself, except I recently picked up an ex-demo red PRS-650 from eBay, and can't really justify a fourth Sony reader
They also have a few older refurbished models (eg PRS-300) in their eBay store.
