Well, this is a huge jump in cost, but if video is important to you, consider one of the DSLRs that have HD video. When you combine the HD quality with the lense capacity of SLRs, you get some really high-end video capability. To me, it makes far more sense to go the high-end HD camera route than to get a mid-range camera and a mid-range camcorder. And it's a better long-term investment, as every lens you get in the future will be available to you for both video and still photography. Plus you can go from photo to video mode instantly, rather than having to search for the camcorder.
We have a Canon 5D Mark II, and I'd put the quality that we shoot with it up against any HD camcorder. Have a look through Vimeo at what's being shot on the 5D for an idea of just how powerful a tool it is:
