You can find an interview with Michael and Laurent the 'Bookeen' guys
here
It's in French of course but even if you don't speak it, you might find it worth looking at for the (unfortunately brief) demo of the screen. It does seem to change pages pretty quickly, at the press of a button.
The price is 350 euros
TTC ie including VAT. So $350 give or take. It willl be sold direct from the Bookeen site, though they have distributers ib Spaion and italy.
No support for pdfs to start with but the interview seemed to suggest that it is in the pipeline. I wasn't quite sure whether this is because they are trying to find a way to get the text to reflow. (I'd be happy with pocketXpdf for the minute!).
Oh and it will support zipped/compressed files.
