Well if you're moving into the DSLR cameras, you have to bare in mind a few things. You'll need lenses, as well as a computer that will be able to handle HD footage.

I'm personally not a fan of the nikon cameras for video. Some other people may disagree, but I find the camera to have a inferior censor than the Canon 7D or Canon 5D. But if your price range is for £379.97, then that'll be tough. The Canon 7D is at least £1,000 body only (no lenses) but you might be able to score it off of craigslist.

The video on the newer Nikons is ok, but Canon's video is still better. The 7D is actually the worst choice of all the Canons for video, though. Look into the T2i (aka 550D), the T3i (aka 600D), or the 60D.

Yup, I was going to say 550d as well. Great price for features.

Al why is the 7d the worst choice?

Overheats much more often, no manual audio, fixed screen, and most importantly.... no Magic Lantern.

yeah I know people taht love the 7d but if I couldnt have magic lantern or be able to see that mic is working i wouldnt be able to function

The bit rate, compression, and audio have more of an effect on video than the sensor.
