Thank you Annah for getting back.
I think I can see the reason I couldn't find any info, it's all on American sites, Barnes and Nobel mainly. The prices are all in $.
Will look around and see if they do overseas shipping. But it's sure a nusance. I found some on a site for partially sited people, not sure what that's about.
If it looks good, all I need to do then is find the small fortune to pay for it.

Adition. Seems Nook has a UK site now,
nook.co.uk Sorry if I'm missing something, but I can't see any sign of the keyboard addon. Is that a particular model?
