Much more valuable to expend that effort on other areas of the robot.

I agree that you are better of buying the solution when one is available. The COTs choices have grown tremendously in the last few years. But one stage is fairly easy with 20 DPI gears. More than 2 stages becomes really difficult. I always take stated accuracies with a grain of salt.
In terms of drill presses. We are fortunate to have a heavy 1/2 press with good bearings. But I get as accurate results by using a 1/4 in Ryobi and either a short 1/8" bit or center bit.
