I think I know the Yamaha guitar Szarak is talking about. In Ottawa it goes for about US$245. and comes with its own gig bag. It sounded terrible compared to my full size Korean Yamaha, but OODLES better than any Uke I've ever held. I never thought to try sticking headphones into the pickup socket.

Travel guitars are only great while you're moving. If you have a stable base camp, I'd suggest renting an instrument. But don't forget your tuner at home as I've been known to do...
