I had the same issue of looking for a small travel guitar a while back, and found a novel solution, here is what happened: I got a little starter guitar for my niece at the local super-store, she was a little too young for the guitar and it was getting trashed so my sister gave it back to me. I re-stringed it and cleaned it and tuned it up, and it turns out it plays great! It holds tune really well, and while it is fairly small and incredibly light weight, the fretboard is still a decent size. Its made by "first act" and only cost like $40.
I started using it as my travel guitar, it plays great, it holds tune, and it is small enough and light weight enough where it can be easily carried everywhere I go, yet it was also so low priced that I do not have to worry about the thing. Its great, it's all the advantages of always having your guitar without the stress and worry of potential damage or theft.
I recently came into a good chunk of funding and want to start buying instruments, I want a banjo, a mandolin, an acoustic bass, and a "Cajun box drum" with some bongos, maybe a "rumba box" and a violin. I have access to a large number of acoustic guitars so I am not necessarily looking in that area.
I want to get together the instruments to record. I record track by track and can play just about any instrument you give me, usually I will write and record an entire album by myself, I also program, primarily with FLStudio, and can use pro-tools and similar programs. Eventually I want to get a band together, which is another reason why I want the instruments, but until I find the right people recording will be the priority.
Also:
If I wanted a "washtub bass" or "gutbucket" I would have to build it myself right? Is building one or buying one the best option? It seems simple enough, metal washtub, a long wooden staff, and a string should do it, but I was curious, does anybody know of any resources which describe optimal techniques and materials for assembling these things?
I am also always on the lookout for good washboards to be used as percussive instruments. Any references on good sources would be appreciated.
