Hi Angela,
I have a Noteworthy County Kerry 24. When I picked it up, I got to spend some time talking with Jeff Gaynor, the gentleman who built it. He showed me around his shop; he does beautiful work with wood!
The Kerry is a beautiful small harp; the difference is one extra string at either end of the range. The rounded soundbox feels extremely comfortable, and it has buttons to attach a strap if you want to play while standing. Mine has Truitt levers on all strings, which are absolutely beautiful and so easy to use.
