I know the Pocket Reader is an old model, but if you're looking for a second reader, something cheap that will work with libraries, PC Richards is selling it for $95, free shipping. You get taxed if there's a B&M presence in your state though.

The price is competitive with many new, used and refurbished prices I've seen. I'd rather pay $10 more and get something new.
