For really impressive videos, especially time-lapse, this would be my route...
panasonic lumix dmc-fz200
I do the bulk of my videos with my older Canon T2i. I get pretty impressive cine-quality from that camera. I do have to work a bit at it, manual focus and all, but the output trumps any camcorder I've owned.

Good luck.
