If your not looking for a couple of bad habits then I wouldn't adopt a parrot. Keep looking into good breeders, I think you'll be happier. Here's are some really good small time breeders

Not really looking for a fight, here, but I think your attitude on this is incredibly unkind, bordering on cruel. This statement sounds as if you're saying that any pet or cage bird that loses it's home doesn't deserve another because it might have some bad habits? So, these animals are no longer "useful" and their lives don't count.
Okay, so I'll just write to my local resuces and let they should just get the euthenasia injections ready for the incoming pets since no one wants an animal who's only desire is to have a loving home. Because it was their fault they were born and given to people who's intrest quickly waned or didn't understand the time, money and effort necessary to keep a pet.
Seriously!
Rescues are wonderful places to find companion birds. The cost is often less than a breeder and as Bobby said, most have been given the necessary health care. And you're giving a loving home to a bird who truly needs you.
