Very, very few DSLR's do video and it's apparently not great on any of them. In the Nikon line, it's only on the D90 and the D300s. The D90, body only, runs about a grand. The D300s is just under 2100 in Canada. Then you have to buy a lens to go with it.

I would suggest you look at a prosumer fixed lens camera like the Nikon P90...all the features you listed, big zoom, lots of manual controls that you can customize, around 500 bucks. Looks like a small SLR, but no changeable lenses.

edited to add...I'm sure Canon makes a similar camera, but I don't know their line. I'm a Nikon girl!
