Hahaha...this particular one with the thermostat and cooling fan will be far from enticing, I'm sure. Hours of milling and quite a bit in parts. Heck dude...the light engine alone is $57 shipped from Russia...then you gotta think 2-4 LiIon cells, charger, connections, switch, optics, lens, snap ring, anodizing, mount, hardware...
It ain't gonna be a $750 Lupine fo sho...but it won't be a $100 MagicShine either.
