I have one hanging on my wall. When I first bought it I really liked it. I think they make a great fill in for a guy who only has room for one or two guitars and wants to have all of the guitar sounds.
Since I took up Violin lessons and Bouzouki I haven't touched it much. I guess it's not really the instrument, just the way I'm using my time lately...so it just gathers dust and probably needs new strings.
The alternate tuning does take some getting used to.
