Not a stick player (not even much of a player, period - I really, really suck
), but I'm teaching myself to play a Mobius Megatar - its the poor man's Chapman Stick (assuming you go the inverted fifths route, at least - I didn't, and went with uncrossed bass bottom fourths instead), and I am absolutely loving it.
Another cool thing about Mobius, besides their awesome instrument, is that their turn-around time on delieveries is waaay shorter than Chapman. I got mine within 4-6 weeks of ordering.
Both Stick and Megatar are definitely not what you'd be used to as the norm... feels like playing a piano sometimes!
