This may not help, and I'm not trying to be churlish, but even if you're "just having fun" with music, I don't know why you'd go FROM a 76 note keybed TO a 61.

I personally think you'll have trouble finding a decent 61 note keybed with your required feel.

Stick with a board that offers 76 notes and you'll find your choice a lot easier.
