That's what I have an use, the ATC2k. It shoot's "ok" video and is water resistant to 5 meters (or something like that). I couldn't pass up the price though since mine was $48 at Sam's here in Austin and the gopro's go for twice as much. The biggest complaint that people have about the GoPro's is the battery life being very short. I've had the same lithium batteries in my ATC2k since I started filming with it....They seem awfully bulky. Are the little "bullet" type cameras not any good?
I picked up the VHold a few weeks ago. My uncle used it on his last ride.If money is no object for someone, you could always try the VholdR CountourHD Camera. Unless someone already has one???
It holds up to 16GB SD card and up to 8 hours of HD video...which is considerably better than the GoPro. Only downside is, this camera only has 135 degree angle lens compared to the WIDE angle GoPro at 170 degrees. ..oh, that and the GoPro is like $150 less...but like I said, if money is no object!
