tank cam?

[mygixxer]

I have been interested in setting up some sort of tank cam or some type of cam on my bike but I know NOTHING about it from the set up to cost. I know I'm not interested in having a rear view cam, but something in the forward direction would be cool. How much would I be looking at for a cheap set up? does anyone out there have a used one that I could get cheap? How does it capture your ride? does it just use a memory card?
thanks for your help

There is an all in one unit that is advertised in/on RW.

how much would something like that go for? sorry if I'm being the stupid rookie to forum chat here, but what is RW?
