It was nice meeting you too! Ironically, I'm interested in the baritone partly because I DON'T play with other dulcimers usually. (Nobody around here!) It's attractive to have a dulcimer that can easily manage G or A, without capoing, along with my D-friendly dulcimer.
I did look at your YouTube videos and heard the difference between the 3 and 6 strings. I like the look of the hourglass shape so that's what I'd probably get. I've been researching and it seems like the red cedar is a really popular top. I'd been thinking spruce, but now I don't know.
