Denno,
I’ve got a Muvi VCC003 which is the smaller less high tec version of what you are looking at. Build quality, operation and accesories are really good and if you shop around good value for money.
My muvi came with 2GB memory card which is fills up rapidly, 8GB gives about two hours filming but that is the maximum memory the camera can deal with, if the hd10 can handle more that would be good.
Helmet mount, handlebar mount, car mount etc are all available, good quality and work well. Underwater kit looks good but I’ve not tested it yet.
From the tiny lens this is never going to win an Oscar for cinematography but for the cost I’m impressed.
I have used windows movie maker for editing, the camera is recognised as an external hard drive and you import avi files, fairly straight forward.
