We have just today started the pre-order for the PocketBook 902. Its a 9.7" eink display, which is the same size as Kindle DX and at $299 is considerably cheaper. PocketBook software is phenomenal for PDF and of course the device supports SD cards. I havent even finished adding all the detail to the page yet. Ill have that done in a couple hours.
More information about PocketBook and the various devices can be found in the
PocketBook forum here on MobileRead.
If you decide to order more than 1 we could offer an additional discount for quantities of 10 or more.
