FWIW (having used Dynamixels for 13+ years for hobby stuff), there are cheaper alternatives with tradeoffs now, too. Though I've only played with e.g. AX-12-sized ones (specifically HiWonder HX-35HM sitting on my desk from early last year)

There's so much to do in robotics, that you won't catch me going back and modifying RC servos, ever. I'll do hard things elsewhere! (And I don't even do autonomous hobby robots...)
