Tanga has a bunch more M-Edge covers and jackets on sale again. The sale goes Sept 4-7, so only a bit more than a day left. Prices range from $2.99 to $5.99 before shipping.
The selection looks a bit larger than last time...with just a quick glance I saw covers for Kindle Fire, Kindle Keyboard, Nook, and Dell Streak. A couple look like zippered cases that would probably work for other tablets and readers with similar form factors.
I have an M-Edge jacket for my Kindle Keyboard and have been quite happy with it.

At the time I'm posting this (8:30 am, US Pacific) the web page says the deals are good for 31 1/2 more hours.
As I mentioned in the OP, I've ordered several things from Tanga, and aside from being a bit slow to ship, which most of these deal sites are, I've been quite happy with them.
