I've been hankering to get one of those hard drive video cameras to find out how much faster you could put projects together if you eliminate that annoying capture step. However, the camera I really want doesn't exist yet (a High-Definition camcorder that records to a hard drive).
As a compromise, I bought the cheapest camcorder I could get, a Samsung SCD-363, which records video to either miniDV tape or an SD Card. The stuff that goes to the SD card is much lower in resolution than taped images, but the fast turnaround almost makes it worthwhile. This was a test piece I put together from one take on a 512 MB SD card.
