Thanks GD, that's just the kind of info that I was looking for and the sort of "quirks" that I'd rather find out about through the benefit of someone else's experience. :027:

IIRC, I believe that you found the 1512 to be more of a current miser also. From the numbers that you posted regarding the current draw of your setups, it might be worth going with the 1512 just for the runtime.

Like I said, Mike told me that he thinks the 1515 would be the way to go, but I have also heard others compare the 1512 to the Lehner 1940 line of motors. If this is a fair comparison, then the 1512 should be just fine. I'll have to think about it a bit more.
