Video Camera Recommendations

A field-worthy hard drive wouldn't be cheap, and the biggest small drive is 120 gigs.

HDV, the consumer HD video tape standard, is probably adequate for most people. It squeezes the crap out of 1080/60i to make it fit on standard DV tapes. Like I said, there are allegedly some artifacts in high motion and high contrast scenes, but I've never played with one myself.

The popular pro HD tape formats, Sony's HDCAM and Panasonic's DVCPRO HD, have very expensive tape mechanisms (and expensive tapes, that go about a buck a minute). That's why Panasonic went to solid state (which is also expensive). You can offload P2 cards to their P2 store, a 60 gig hard drive device, or directly to a laptop. The camera I have can have two cards at any time, so you can pull out one while recording and off-load it while recording on the other. I admit that this is not always an ideal scenario, but it does work.

What type of bandwidth do these cameras/storage mediums need in HD?

100 mbits for DVCPRO HD, and I think (but I'm not sure) that HDCAM is 90 mbits.
