Regarding the deal alert in Post 857 of the BLF Deal Alert Thread. for the TN31.
That seems like a pretty good deal. At one time it would have been a very good deal. I would rather spend $40 more for a TK-61 though. More battery capacity, larger reflector, more heat sinking, and more moddable for higher voltage emitters like the MT-G2 and whatever comes out in the future.
