In response to the hair light on a drop ceiling, Lowel sells (I think made by Matthews and many others) a scissor-type clamp that clips onto the drop ceiling, and has a 5/8 stud to get a light onto. (Safety cables separate of course). This thing ROCKED when I had to setup quick talking heads in conference rooms. A bag of these, one to hold a Rifa, tota+umbrella on a stand for fill, and one more for the hair. Carting in one stand instead of three? AWESOME.
edit: found.

As far as LED's, I like them in limitation but find myself breaking out a tungsten kit just because it's predictable, with the right filtering its dimmable (compensate for warmth when you turn it down), and I know skin tones respond to it. Fluoros are getting cheaper but they're not the easiest to dim, and the ones that are, probs aren't in budget.
Under $1k, the Spiderlite kits are good for a basic two light, or a Rifa for main, Omni+brella for fill and tota for hair?
