These darned things are getting as bad as cigarettes.
Doesn't look like it's stock, but I have a D10 R2 ordered from 4Sevens.
Oh, yeah -- a $1 pretty blue 2AA Rayovac incandescent (2 cells included) from Walmart, and I bought a Brinkmann 2AA LED swivel head for my sister&husband. Cheap incandescents are addictive too.
