Hi Simulator. If you want to buy a "pro" camera, then theres plenty about. I am a big fan of the JVC GY-HD110U, which I know sells for around about 2000-3000 quid. So if thats out of your budget, look at the Cannon MiniDV range, which consists of camera such as the XL1s and XL2. Also comming down to the lower end of your budgets there is the SONY HVR-HD1000E, which again is HD.

All the HD cameras can record onto MiniDV which means your editing sytems will not need to be updated. But the advantage is that when you have more money to spend, and the format becoems more popular, all you need to do is upgrade your editing system rather than the whole lot.
