I am a guitarist but would like to pick up a synthesizer. I want something solid with a lot of sounds that I wouldn't grow out of quickly. Dedication to the instrument is not an issue, if I buy it I will use it every day, I am not worried about it sitting around unused. I found a new Roland Juno Di that someone purchased 5 months ago but only used once. It is in its original box with all the packaging, cables, manual, everything. Is this a good price and keyboard for my situation? Your input is appreciated.
