See, I've got three Pocket Wizards. Expensive but VERY reliable, and work to a crazily long range.
I usually have one on the camera and the other two on the lights. Sometimes I only use two if the strobe will optically trigger the others (and I'm lazy).
But PW's are damn expensive (like USD$180 each), although you can get some pretty cheep e-bay remotes. Don't expect them to work well though.
I think if I had the chance I'd go for a set of Radio Poppers [link]
