Just a heads-up (which I posted in another "light" thread!): Barnes & Noble has the 3-led 'z-light' (see posts #52 and #69 of this thread) for only $12.99, plus there's an online printable coupon for 30% off. Total with tax is under $10. And you can get the CR2450 batteries for under $1 each on ebay.
This light is pretty bright, very good for regular books. (Still waiting for my Sony reader - damn you, SonyStyle, for your slow order processing and shipping!!!) A big plus is that it is very tiny when folded flat, about as thick as a box of matches and the size of a somewhat elongated business card. Portability is important for me. Several of the other lights posted here are simply too bulky.
