hey, clashmatt23, you can check TheMonk's "DIY Red Burner 1xAA" in the red lasers section, i think it is pretty good stuff and it is for sale now. good luck!
i've been watching this forum for quite some time (as a guest), and yes i agree, TheMonk makes nice stuff, check his for sale "Red Burner powered by 1x 1.5v AA", highly recommended!
