I have a 200mW red, DD 445nm, and ~120mW 532nm in gunmetal L2 with custom heatsink from FlaminPyro on LPF.
A user JayRob on laserpointerforums sells L2p laser kits.
radiantelectronics stocks heatsinks for ultrafire 501b (generic p60 host, so maybe it might fit others? site should have exact dimensions) and aurora/ultrafire/"cree" c6
That should be enough to get you headed in the right direction. You will probably want to built it yourself, since it can be very difficult to get even the materials in the mystical land of Oz.
I tried to drum up some interest here for laser P60 drop-ins, but it didn't catch so I just made my own customs.
