Cheap encoders

I might be wrong in this case... but if I were building a machine of some kind, I'd probably try to save money elsewhere on a less critical part... maybe buying cheaper limit switches or something else that doesn't need to be as precise... or maybe buying looser tolerance bearings if you don't need super precise shaft positioning...

That's my 0.55 Rubles.

It is a good thing these will mostly be used in my own Vex robots, or maybe a motorized recliner operated by my lil' Arduino.

I will also use them to help my programmers get familiar with encoders and their usefulness, as you mentioned. But, you are correct, when it comes to the competition robot, reliability is paramount. (Oooo, there's that word again )
