If you need a mic with battery have you considered the Rode NTG-2? I have the NTG-1 (same mic, no battery) and like it better than the ME66 I had before... Of course, I'm more thrilled with the NTG-3, but that's a bit more money (and what I replaced the ME66/K6 combo with).
Thanks for your input. I'll honestly buy whatever anyone is willing to sell to me. I just need to replace it; I am trying to remain calm instead of going on a rampaging , Liam Neeson inspired manhunt for my mic...
