I don't play the harmonica yet ... but I ordered one from Thomann and it'll be here early next week. It's their own 16-hole Chromatic 64 model.
I work in quite an old, large building with whole wings that are unoccupied, and I'm often walking about, so my idea is that I can carry the harmonica wherever I go and try things out in-between other work. I find myself wishing I had some instrument on me to try whatever happens to be running through my head that day.
A Chromatic makes more sense to me because I'm already moderately musically-literate, and the Solo tuning looks sensible. I don't see myself playing much Blues, Chicago or otherwise, though I might try that later.
