Sun conures
they do have a medium to loud squawk I have heard there squawk at pet stores
i hear they are great birds loving,playful,funny.ect..
Have you thought about a rescue?You could find a great bird at a bird rescue and the people there could match you with the perfect bird
you could get one form a breeder i bet it would be a 100 or two more then if you get one at a respectable pet store
do some research on the perfect bird for you
hear are some i think you sould look into if you want:

green-cheeked conures
senegals
peach-fronted conures
maroon-bellied conures
