If you get the Tuff-Luv case let us know what you think of it. I was trying to choose last night, and it was a choice between that and the one I eventually went for which is just a leather envelope sleeve:

I finally plumped for the latter as I've always been happy keeping my readers just in a sleeve before and I like the light weight of the reader without a cover, however, I suspect that when the sleeve arrives it might be too thin to afford enough protection, and I might eventually get the Tuff-Luv as well.
By the way, I've been using my black 650 for a week now and it's great - you're going to love it. Not only the best reader I've used yet, but unexpectedly the smallest (I was astonished to find that this 6" reader is marginally smaller than my 5" Elonex).
