Sorry to hear about your old guy.
It is really hard to find a new one, IMO, especially for those of us that can only have one, maybe 2.
I have tried is all, basically, and finally found my old guy years ago from a reputable breeder, who happened to have one I could afford. Have had him 17 yrs. When it was time to start looking at something younger as he had some arthritis, it was hard, since we were so used to him. Nothing was ever just right. I bought a couple, that, sadly did not work, mostly from traders. Finally got the one I have now from word of mouth, friend of a friend of a friend sort of thing. He is perfect, and his previous owner(s) are always interested in his progress. I could not ask for more.
Take your time, there are SO many out there, be careful, and take someone with you to look who knows you, your abilities and what you want and need. Someone who can be the voice of reason, while we are falling in love (if you are like me) with every pretty face.
Good luck, and remember, the more you look, the more you learn about what you want, need and about yourself.
Have fun, most of us don;t get to do this often!
