Yeah, I have to think this over well. It is easy to get carried away
One thing that is interesting is that the large DMM motor is rated at 2.9 N.m, but the max RPM is only 1080. The large Keling (KL34-180-90) is 1.6 N.m but goes to 3200 RPM. So the DMM with a 1:1.8 reduction is equivalent to the Keling with a 1:3.2 reduction. But at those reduction ratios the Keling reaches 200 IPM with a 5 TPI screw and the DMM tops off at 122 IPM.
Did I get the concepts right?
So far I have not found any bigger (or as big) servos in this price range.
