My light cover is packed and waiting for UPS to pick it up tomorrow. In the meantime, I went to Borders and bought the standard cover for the the 600.
Doug, I have that exact same clip. For some reason, I never took to it, but because the clip is nice and flat, plus light weight, it does go nicely with the reader. I also have the MightBright Flex 2 which is a fantastic light, but it's too heavy and bulky to use with the reader which is why I tried to find the the MightyBright TravelFlex and PocketFlex. I only found the Flex2 at Border's and B&N today, so I ordered them online. I figured they're cheap enough to buy both and I'm sure I'll use them for the reader or reg. books.
In the meantime, I took some more, albeit not the best, pictures to see the difference that a decent light makes. Although the first pic isn't clear, what you can see is that the $10 clip light actually illuminates the page, which the $60 Sony light did not.
Sorry, I had to get a gorgeous kitty shot in there.
