I have this one: Proporta Case & Windshield Mount
It's a great leather case, with leather 'brackets' on the left & right that hold the Touch securely in place and let you keep the flat-screen functionality of your device intact. What I mean is there isn't leather framing the screen, creating a ridge that detracts from the 'touchfullness' of the screen. There's a magnet inside the layers of leather in the back that grabs on to the magnet of the matching Proporta windshield mount. Strong magnet, my Touch stays in place even over a stretch of cobblestone.
Both are reasonably priced, and the case is great...
