We just upgraded our video lighting. If you have the time and want to do your own research, check out
www.dvxuser.com and go to the "lighting" subforum, lots of excellent info there.
I spent a ton of time reading and researching and talking to various people, what we finally decided on was to go with compact fluorescent fixtures with daylight balanced lamps. This has the advantages of MUCH lower power consumption and heat output (we can plug 4 lights that put out the equivalent of 1500 watts each into one 20 amp circuit with capacity left over) and very soft, diffused light that doesn't create harsh shadows.
The fixtures we bought were from Fotodiox

and then we bought 5100K fluorescent lamps separately (about $8 each)
The first shoot we did with them was in January, and the lighting is the best we've ever had... even light with no shadows, natural looking skin tones, overall we are very happy.
I think the fixtures with lamps, softbox, and stand were under $275.
