My conscience would like to make a statement: Rotary encoders, pretty much the most necessary sensor in a high performance motion control system, are probably not a place you want to cut cash in your robot.

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.
