$62 for a single 5W or quad 1W Luxeon kit
I bought a couple of these regulators, six 1W Luxeons, and some lenses to play with. ($115) I'm going to try making my own lights.

One of the issues to investigate will be whether generic AA NiMH batteries will be happy pushing 0.75 amp through the system without overheating or voltage droop. The docs I've read suggest that's getting near the upper limit, but still in the safe zone. Otherwise I can just get a brutish 4000 mAh 12V NiMH battery pack w/ charger for about $30 from batteryspace.com. Yay, new toys!
