You may also want to consider Elinchrom. I have the entry level D-Lite 400s, but you'll probably want to check out the RX600 monolights and then the Skyport wireless remote system that let you control multiple strobe settings right from the camera.
I have no personal experience with this setup, but here's a review from Scott Kelby
link that's pretty compelling.
Good luck with the decision!

I agree! Those Elinchrom RX600 lights are sweet- consistant light temp, fast flash durations, and Skyport remote convenience. Would make great studio lights on rails or otherwise because of the convenience of remotely adjusting the power from the camera or computer.
Also check out Dyna Lite Uni400jr kits if you do location. Not cheap but very reliable too. If you are going to consider Alien Bees because of the price I'd spend a bit more and get White Lightnings instead as they are more solidly built with metal cases and are made by the same company. However AB's aren't a bad deal and great for the money but they aren't in the same league as Elinchrom's, ProFoto's etc (but then again your clients won't be able to tell what brand you used). WL/AB (Paul Buff Products) do have excellent, possibly the best in the industry, customer service. I used WL's for years and have no complaints. I use Dyna Lite Uni400jr's on location and love them for that purpose. The light temp of all the above is not as consistant as Elinchrom/Profoto systems but it all depends on how critical you are or want to be.
All the above are monolights. Pack sytsems- Profoto at top end, Dynalites mid-range, and White Lightning Zuess in mid-low price range.
