I got an Ozark travel guitar latt year in Glasgow for £125, and it has been a great buy. It looks rather like a tenor mandolin with a 7/8 size guitar fretboard. It plays very accurately, nice sound, though not very loud, so it's better suited for practice, or a small group in a quiet setting. It comes with a strap and a soft flat rectangular carry bag, which rather resembles a rifle case. You should see the airport security staff gathering round the x-ray machine to decide what it is! When I offer to play them a tune, they let me through without further delay. It usually fits without problems in the storage over the seats. When unzipped in public, it usually attracts some interesting comments, and provides opportunities to pass what would otherwise be very lonely spells in hotels, stations and airports. Apparently there is also a version with a pickup, if you really want to be heard.

I'm rather surprised that no one so far has mentioned the Ozark in this thread.

Before anyone makes the comment, No I am not an Ozark rep. I just found this little guitar to be just what I needed when travelling.
