NewEgg has the JBL for $99, free shipping, and free leather case.
http://www.borders.com/online/store/..._libre-ereader has the Libre for $99 through Nov. 15 (in one spot on the site it says through 10/31, on this page it says through 11/15).
I'm favoring the JBL because it has a built-in dictionary and the foreign language capabilities. Am I correct in understanding that 1) you can click on a word as you're reading a book and the dictionary "pops up" with a definition? and 2) you have the option as you're reading to click on a word and see it in Spanish (I'm interested in learning Spanish) or, conversely, to read a book in Spanish and see a word in English? These are things I'm hoping to be able to do, so if I couldn't do these things on either a JetBook or JetBookLite, I would just choose whichever brand I found at the lowest price.
