I want to try and learn to play the piano... and I want to get a decent keyboard. Anyone have a good suggestion? Price range... I'd like to keep it under/around $400. I'm sure that'll limit me to just beginner stuff, but that's probably all I need since I'm just learning. I'd still like it to be a decent one, though... maybe MIDI capable so I could do extra shit with a computer... Any suggestions on brands or models?
