Hi...

I'm seeking a good SD/SDHC media video recorder to use for capturing video input from a bullet cam on my motorcycle.

I really don't intend to use it for any purpose other than capturing the bullet cam's input...so standalone camcorder capability is not important (and purely optional).

I'm aware of options like the Aiptek Action-HD camera...but am wondering what else is out there.

The two most important criteria are:
a) external video input
b) good battery life and/or ability to run from AC power

Because I'll simply be capturing the bullet cam input, things like zoom capability are irrelevant. Even audio isn't very important, as i'll be laying in my own audio in post-production.

Any recommendations are appreciated!
