Quakers make a very annoying type of sound. Worse than sun conures, in my humble opinion. How often they make that sound varies by individual bird, but I cannot stand that sound!
Dusky conures are not as loud as suns but they are still loud. All conures are loud. Remember that all baby birds are pretty quiet, but that will change as the bird gets older. $250 is a reasonable price for a handfed dusky.
Caiques are fun but the price is pretty high. I heard they can get very very nasty once they reach sexual maturity and they are also prone to plucking. I know that can happen to any parrot, but I heard Caiques are pretty bad.
I think a Senegal parrot would be a good choice. Or any other parrot in the poicephalus family. Senegals are the most common poicephalus, I think. They are pretty quiet too.
Did your cockatiel give off a lot of dust? I used to have an African Grey and all my stuff was coated in dust! I should have bought an air purifier...
Greys are quiet but they learn sounds very well. The fire alarm in my apartment went off one time and the bird memorized the sound. He also knew my ringtone and the microwave beep. He would make these sounds all the time. It was cute at first but got annoying, especially the fire alarm sound, lol.
And in case you are still considering a severe macaw, they have a reputation for being a bit difficult.
