May I suggest that you purchase the camcorder of your choice based on its many other features first.
If you can afford it I would suggest that you have DV in and DV out, then you can edit back to the camcorder (usefull).
If the camcorder has firewire, then install a firewire card in your computer(about £25).If it only has USB then you have no problem. If it has both USB and firewire then install firewire card ( I think personally that firewire is better)
