I went on my bi-monthly pawn shop run today (I look for guitar stuff...pedals etc, generally) and saw a used Yamaha PSS780. Now I don't play keys, but from what I understand it would be a good idea to have a keyboard around for midi and stuff. And yes I am a total newbie about this stuff and I basically know squat about midi and synths etc. Anyway, I could probably pick this thing up for about $50 CDN. What attracted me was that it had midi in/out/through and drum pads. Everything works on it. Should I pick it up? It would be mainly for learning purposes.
