In reply to NathanW:
Your best bet might be to watch some comparison videos on YouTube.
I got a Sony CX-115 (£275) a couple of years ago and use Sony Vegas to edit. One word of advice, check the file format the camera saves the video as - Sony & Panasonic cameras generate .mts files, which aren't readily editable out of camera. This is the reason I went for Vegas as an editor as I can do so without translating to .avi or .mp4 first. Not much is going to beat Adobe Premier though!
Also, I bought a 3rd party wide angle lens off Amazon for about £30, which has a really good macro facility too, if you 'split' the lens and is something I'd recommend.
