Yeah, I have a camera that uses them already.
Key issue on that is I really only want to record in about 30 minute bursts, but I need to control it. If it was hard disk, I'd simply ignore it and let it run.
But with a remote, I can control as needed.
I'm waiting on the guy to get back to me on my offer.
I've got a fallback lower end I'm looking at as well:
Panasonic SDR-H18 30GB HDD SD Camcorder 32X optical with OIS - $175
I might end up with both Panasonics.
