Okay, I'm new to recording and am just getting used to GarageBand, but I think I want to add a keyboard. I want something affordable, compact, and easy to figure out. No need for lots of bells and whistles (GarageBand has plenty!). I would prefer a model that can also serve as an "audio interface" for guitar and microphone, with headphone jack. If the keyboard also had the ability to be used in a live band application (i.e. plugged into a PA or amplifier), that would be icing on the cake.
