I'm not sure why you're contemplating between a travel size guitar and a full size dreadnought as they're so far apart in terms of application and character but if you want something inbetween I suggest the Taylor GS Mini.
Hi i've actually tried another called Dove DT-220 travel sized guitar. It's sound is amazing and it's quite well received among my guitarist friends. It's quite a new brand so it doesn't really have much exposure. It's tone is definitely comparable to those of earth mini and baby taylor, best of all, it is very affordable!
It is currently available at a guitar blogshop in singapore, just look up dove DT-220 travel sized guitar in google
cheers!
