I have a Washburn Rover.

As others have said, it's a bit light on the bass (but almost all travel guitars will suffer from that). However, I really like the neck...full size, with 19 frets and not at all cramped like a Martin I tried a whle back.

I have medium strings on mine and it doesn't seem to have suffered from it. The case is fine for aircraft luggage racks, but to be honest I'm usually walking with mine so I just wrap an old bit of foam camping mat around it and shove it in a rubble sack which I strap to my backpack.

I wouldn't dare do that with a really expensive travel guitar, but am happy to treat the Washburn that way. As an all round "value-for-money" option which you don't need to worry about cossetting, I think it would be difficult to beat.
