I highly recommended you to "steer away" from going to HD format at this moment.
Reasons:
- the MiniDV tape for video bitrate is 25 Mbits per second, which is a high lossy compression for HD. The video degration will be noticeable after generations of rendering/editing.
- Cost. Still too expensive imo...
So, if I were you, I will would pick the original MiniDV if you don\'t have that already. A 3 Chips 1/3" MiniDV is really good at the moment until there is a HD camcorder that supports bitrate higher than 25 mbps for consumers. me, I prefer one running at least 100 Mbps or higher for way lesser compression ratio and better color sampling.
