Mike,
Julio has told me about Carl's place in San Diego. Carl had a big factory in Thailand and I use to buy lots of made jewelry from them about 6/7 years ago. Along about that time, I made a big investment in all state of the art manufacturing based on CadCam technology. All my business with him has been honorable and have a good relationship with Julio even if I don't do much business with them anymore!
I have no experience with them in their new venture but think that they are good guys.
Good Luck,
Dan
