If you ever want a motor that can do any high torque job for <$5 go to an autowreckers and try a windscreen wiper motor. They are amazing.

You should already have in mind the performance of these super cheap motors. Think of the torque of a the top of the wiper encountering newly fallen snow/torrential rain/leaves that they commonly have to overcome. They internally have metal gears, are high speed and are designed to be maintenance free.

I've used them for automatic farm gate openers, wire spoolers (spinning out 2 ton spools of fencing wire with no further gearing, just a good flat bearing holding it) and a bunch of other contraptions over the years.

also could have used a worm drive gearbox, they also have high torque, and possibly a rotary encoder for sensing position.
