Entry level price for an e-ink device in the UK is now down to £35, i.e. US $55-60, of which 20% is VAT (tax); in the USA it's down to under $50 (in some cases $35 with a mail-in rebate). Furthermore, this is the retail price for the reader. Unless they're heavily subsidized to below cost price, the device itself is even cheaper.

I would only use the e-ink technology. All other features wont be necessary. So really the most simple version of an e-reader will do.
