I just spoke with Mr. Boulding the other day, based on Biagio’s recommendation. (See, I do listen!) His website is ‘down’ at present, being re-done, but he sent me an updated (2020) price list.
Harps are made one at a time. They are quite reasonable, by comparison; however, harps do not come ‘complete’ as other manufacturers’ packages (e.g., DS, L&H, Rees) -but are custom-made, with as many (or as few) sharping levers as you may desire. Cost changes per lever, plus additional cost for a case.
(which I am not a fan of- of course you need levers and a case!?)
He’s sending me sound samples. I can hardly wait.
