I finally received the refurb MMM ESC I ordered on July 28, 2009. It took over a month but what the hell.
Anyway, I opened it and was actually disappointed by what I saw. The battery bullet connectors were soldered together which makes it impossible to open the ESC when replacing/removing the cooling fan.
Here are some pics:
I think it was soldered by someone who really doesn't want to do it. I'm not an electronics/electrical guy but I can do better
