I used to have a DOVE Sphinx, made by Rodger Frood, a truly fantastic instrument, held its tune so well, it was stored under the bed for 18 months. Took it out, still in perfect tune! They are a bit pricey (Thick end of £1000) but you get what you pay for, and I believe they are the best in the UK. If I had the spare cash I'd have another one tomorrow. He also makes bass dulcimers which are PDG too!
