Umm…. you seem to have A LOT of feature requests for a cheap camera.
if you want DVCAM and HDV… then Sony is really your only choice…. although I don’t think the HDV can switch on the fly (liek decks can)
Speaking of decks
DO NOT USE a CAMERA AS A DECK
You can get a dedicated HDV and DVCAM deck for $2K…. You’ll never find a camera that cheap. But if you trash your camera heasd by shuttling and rewinding.. you’ll spend more than 2K geting it fixed.
I suggest you start at B&H and look at Sony HDV cameras and see what matches your numerous feature requests.
