this is only a test project .. i'll get the $$ ones later

If you are OK with electronics you can get a couple of Anolog Devices AD724/725 encoder ICs free of charge for evaluation/sample purposes, they work well for MVS but can be a bit flaky on some jamma boards (like most if not all encoders to my knowledge)
