As I am on the road a lot because of work, I have also tried out a lot of guitars that fit the description.
Right now I own a Ultra-Light Electric from Traveler Guitars (I think Justin also recommended that one on the old forum a long time ago) - but I have to say that it feels too small for me and it does not make me want to play. But: its very small size makes it possible to just throw it into your luggage or even checked baggage.
If size and space is not the biggest issue, and your not likely to travel by plane, I would also try out the Yamaha CSF3M. In terms of size its comparable to the Taylor GS Mini, but it is all solid at the same price. Tried it out in the store and immediately wanted to buy it. Since I am mostly travelling by plane I refused the urge
