Not sure if he would be willing to do another one but I had bought a LED that was placed on top of a lumens factory aluminum drop in body. Carbine15 had made it and sold it along with a E head a little while ago. It was direct drive with a resistor and put out about 30-40 lumens and was avery nice smooth beam. It was a XP-E I think or maybe a XP-G can't quite remeber. I sold it but maybe he would be willing to make another for the right price. It is not quite as good and custom as Koala's but I liked it.
