Still have the dead m50?..pm me i might buy it from you.This mod lost all relevance with the non replaceable batteries. It was nice when it was a single battery replaceable. Small, did 50 watts. Now it's almost the size of my Sig 100w. I'm so glad I just bought a Sig 100+ to add to my collection. 2 batteries, runs for 2 days, can fire to 100 watts if I need, which I don't. I won't miss my dead M50.
