Don't get the special offers Kindle Touch but the other one at $140 and all of a sudden the lighted cover is less than 45% of the price. Much better value than if you compare it to the special offers version!
Seriously, the point that it is what value it has to
you that matters! For
me a lighted cover would be far better value than an Oberon cover (since that's seems to be considered a fair comparison for some reason).
(I think the lighted covers for the Kindle Keyboard are much prettier than the new ones though.

The light looks much better on the new ones though.
