5 months and 11 post , and you still haven't made up your mind? Is there something specific you want to know? It really boils down to:

Hard Facts:
Price: how much you're willing to pay.
Weight: how much you willing to put up with.
Availability: can you get it.

Relatively Subjective:
Power: how much you want. There are plenty of post 'round here on tach numbers.
Customer Service: Everyone has an opinion, but that's all based of someone's level of expectations in the first place...

Myself, I purchased a used BME102 for my H9 Sukhoi. It's my first GS and I wanted a twin for the cool factor and tend to root for the underdog. I would have been just as happy flying it with the ZDZ80 I'm sure and I think the DA is a great piece of work too. You cant go wrong with any of the choices. As Nike once said Just Do It
