If the MM is working for you, why are you going to mess with a good thing? So far, I've had the best luck with the MM controllers. I'm on my second Quark, and after a month, I still have no word from MGM on my 16016 that I had to send them, due to software issues.

MGM's customer service is mediocre in my book. Sometimes they return emails, sometimes they don't. There is definitely a bit of a language barrier and if you send your esc in for repair, good luck. Mine's been gone for a month and I can't even get a status from them.

I was running the MM (I have five of them) and decided to "upgrade." I bought both an MGM and a Quark. Right now, the only ones still running are the MMs.
