Accordion joke: It's the Law: USE AN ACCORDION, GO TO JAIL!I'm with Alison on this one. I used to have a full sized job but I never got very good on it. It was like strapping on the front end of a Chrysler, so I never felt much like practising with it.
So now I have a little one with two octaves on the right and 12 buttons on the left. That is, 6 bass and 6 chords. All the chords are major, but I can get 3 minor chords out of them as well. This is plenty for folk music. Moreover I enjoy playing it, and even practising!
For cajun you would need a special kind. I have seen them with buttons and I think they probably have special reeds because they sound different (and louder).
Good luck with your squeezebox. == Johnny in OKC
