Where to buy a bird

Ever since my parents sold my conure (I was away at college), I've been lonely for a bird. Where is the best place to buy a bird? I bought my 2 childhood parakeets at a hardware store of all places, and my conure at a run of the mill petshop. However, I'm concerned that a petshop might not be the best place to buy certain types of birds. I've looked on the internet, but haven't been able to locate any breeders in my area (I live in Phoenix, so there should be breeders somewhere around here). How do I find some local breeders, and is there any way to find out what their reputations are?

I'm still exploring what kind of bird I should get, but I just want to be prepared when I decide.
