Now, to come back to the question at hand, yes it seems that a Poicephalus might be an ideal bird for you.
As Izver pointed out, I live in an apartment as well and have 5
Poicephalus (and a Lovebird) and have never had a noise complaint. While they are able to be noisy, when put in comparison with other species of parrots, they are on the quieter side.
They are all playful in their own way, but I have to say the Red-bellied, specially my male, are more playful with people (whereas the others like to play on their own). Red-bellied parrots are also big show off birds - even Izver's Lucy, whatever she might say, when I came over to see her birds back in November Lucy was definitively the one who was being more social with us

As for breeders...well there used to a be a good one in my area but she stopped breeding. However, there in one in the Guelph area who I believe is willing to ship her babies. Earlier this year I was contemplating getting a baby Red-bellied from her, but it turned out her clutch was only composed of males and I wanted a female. Had Pixel not been put on my path, I would still be waiting for one of her babies - I went to visit her home and was quite impressed with how her bird pairs were kept and what she fed them.
She breeds Brown heads and Red-bellied parrots in the
Poicephalus family, and also has Dusky, Blue headed and Bronze-wing Pionus, which might also be a good fit for you. (Ironically, I believe quite a few of her breeder pairs come from the Vancouver area..)
