My research says I will probably be getting the Alien Bees for studio lighting sometime this fall when I need to go back indoors. (Currently saving money for trip to Jamaica).
In the meantime, I get by with a couple of Home Depot worklights and a couple of continuous studio lights a 150 watt and a 600 watt (which is way too powerful except to reflect around the room). Those and my pair of 550EX flashes. So far I have gotten the best studio results with an off-camera 550EX and one worklight.
The nice part of the 10D is you can adjust the camera to your lighting to get the desired effect probably easier then you could with film. While yes the sensor is probably more sensitive to light differences then film, this can be corrected via the camera or in Photoshop.
It probably does not matter what you use, but in my case I decided I want the flexability of good studio lights and the alien bees seem to give me that, so as soon as I have the money they are my choice.
[note: I would have considered white lightnings also, but can never get the site to come up for some reason]
Just my opinion and research.
