HD Cameras have been the biggest drain on my bank account, ever since I bought the damn camera. Unless you are buying a more top-end camera, and have a damn high specced PC / or a MAC I wouldn't suggest it. At £400, you will get on so much better looking at Standard Definition MiniDV cams, preferably with 3CCDs. Have a look around Amazon ect and see whats available at that price range. New cameras at £400, you will get a good choice of highstreet names, and are all much of a muchness, so just look for features that appeal to you. However if you want to venture into the 2nd hand cameras, you will get a lot more for your money.
