Did you get one in the end Bob? If not, take a wee look in Borders. I saw they had some e-reader reductions amongst the melee that currently is their shop floor.
There's no Borders near by, closest one is in York I think.
After looking around I figured a Kindle would be the easiest choice and ordered one yesterday, but after reading up on a lot of different readers I've cancelled it, decided to wait for either prices to come down or better devices to come out.
