The best guitar emulation Ive heard is right on my Roland XV5080 but its so expensive. I would lean to a keyboard/work station cause you can do so much with one. Youll have to decide what you want to be your main instrument - the guitar of keyboard? I couldn't decide so I play both. But I started on drums when I was 4 years old, thats right I leared to play the beat before I could even play one note on a keyboard or guitar. I think you should learn both the keys and the guitar then you wont have to rely on anyone to help you.
