yeah, dont be buying them lights. You WILL regret it. I think the ideal situation is to do what previous poster suggested. But if your going to spend that kind of money you should just buy the track IR.
I recomend this.

Honestly. My setup works great. But im not impressed with the feel of the head movement, so I dont use it. I know it sounds all great and cool and all, but till your actually able to use a device... well you get the idea.
I will sell you my whole setup, camera and all for 40bucks. Where you from?
