Instruments- discuss specific features, luthiers, instrument problems & questions
It's a good question and you have received good answers. In the end, what is most important is that the dulcimer appeals to you and makes you happy when you play/use it. If you don't like the instrument for whatever reason, you aren't going to play it. Some people like fancy inlays and bindings, others don't. Some like hourglass shape, and others don't. If hourglass dulcimers with beautiful woods are aesthetically pleasing to you go for that, because that is what you will enjoy playing and it won't really matter whether you have a flat or scroll peg head.
