I was thinking of picking up some AMC servo drives off ebay (BE12A6
drives seem to be cheep and plentiful there).
Mesa 8i20 is cheaper, do not know about Pico drives.
And paired with KL34BLS-98 ($134/pcs) servo motor it should be a good
match:

That is what I was thinking, the existing motors are quite old and are
probably not as strong as they should be either, so if I am buying new
drives and motors anyway, I thought switching to servos would be a good
idea, especially since I would need to get some sort of hardware step
