I have bought 3 Chondros from http://www.frantzherp.com/
Never had any problems with any of my babies from him, I sold them awhile back but nonetheless I trust him. I have heard he farm raised his. But I'm not completely sure.
Either way if you want a really stunning GTP spend the extra money and get one from http://www.signalherp.com/index.html
They are worth every penny.
