Price Drop on GoPro HD
This is the full 1080 version, not the lower end 960 version. The discount also qualifies for Prime (get it in 2 days free shipping). The GoPro HD (basic kit) of course comes with the standard waterproof housing, but I suggest you also look into the (optional) tripod mount which is what I find myself using the most.
The LCD BacPac is also a very helpful addition too.
