What are the best dulcimer kits?

Hi folks.  I need your help once again.  I have a beautiful all-cherry McSpadden teardrop dulcimer.  I have some woodworking experience, and I'm toying with the idea of building an hourglass instrument.  I'd like your thoughts on the best kits out there.  I don't have the time or inclination to build one from scratch.  Thanks in advance.
