I think the Sylvia Woods books are good – sometimes the fingerings are odd, and I don't personally like her hand position, but mines not "perfect" either.
I think my teacher, Geoffrey Ricketts , will be publishing his method soon, which I think works well for a folk music style approach.
I have 2 folk harps, shown here, I really love the Dusty Strings and the custom Mountain Glen. Both have sharping levers on all strings. Little Hawk, did you ever get a harp?
