Got one from the last sale, and I've been satisfied so far, for the price. I've made a few runs with it strapped to my 50mph RC car, and it's held up as well as one could expect. The picture quality is just fine for the amateur stuff I'm using it for.
It comes with all kinds of neato attachments, and the case seems secure enough, but I'd rather not perform a bunch of drop or crash tests to push it.
The screen is nice, if only to help mount the camera and housing; I don't rely on the use of the remote, and the touch screen is cheap so don't expect precision poking. The vehicle video mode definitely makes a huge difference for shooting hi-motion shots too, so make sure you use it!
One other thing to be aware of: make sure you get a class 10 microSD card! Anything less probably won't work, I tried an older one I found in a drawer and it wouldn't register. I would suggest getting at least 16GB, if not 32GB, which would probably give you full record time before the battery dies.
