Replacement push encoder for NI kit?

Replacement push encoder for NI kit?

Anyone know of a good place to pick up a replacement push encoder? Picked up a Mikro on the stupid cheap ($50). Encoder and screen are busted. Everything else works like a top. I’d like to find a replacement and fix this puppy. Screen would be REAL sweet, but I won’t push it.

As long as you know what is an encoder, how it works and how to make some measurement, digikey, mouser have it for sure.
