A twelve-string program looks the most likely solution... :-)You want a travel guitar, get a cheap half-size and a cheap case for it. I bought an ultra-cheapo £30 job from Argos (UK catalogue store, for those in the US) for my wife to try to learn on, and amazingly it sounds just fine, plenty good enough for practising on (and the string spacing on a 1/2-size classical is about the same as on a normal electric). It's a damn sight better than those crappy Martin Backpackers - I can only think that ppl who voluntarily play Backpackers have _really_ been away from guitars for a long time, to be that desperate!
