Hello Renee, and welcome to the Chordie Forum!
Well it seems you have the only one in existence! So I hope you will be happy together for a long time. Now you will have to get back on e-bay and find a nice glass display cabinet to preserve your rare find.... LOL.
Actually I'm rather surprised that you have not had any responses from the membership so far. There are a lot of us out here in cyberspace, and surely someone has a Gurian. I did do a little reading on the brand as it is a new one to me, and they are a very fine instrument worth every penny of the price you might have paid to regain yours, according to several sites I visited which had reviews from owners. One thing I didn't do was search for a Gurian Owners Group. There might be one out there where you could touch bases with others that are loyal to the label, and, naturally stay tuned here on Chordie! Among the 300+ thousand registered members there are bound to be a few hanging out there in the shadows.
Once again Welcome to Chordie!
Visit often and don't be shy about posting your comments, questions, poems, songs or whatever is on your mind here on the Chordie Forums.
Take Care;
Doug
