senegals and red bellies are nice and fairly quiet for the most part. some of the other suggestions are good too.
my keets were little chatter boxes most of the day, not loud though, just constant. the more noise they hear the more noise they make. they are just the cutest little things! but they make it hard to watch TV or have a conversation in the same room with them.
my sennie is pretty quiet except when she is calling for me, so i just take her along when i leave the room and she is happy. she is not much into toys but you can find great stuff at yard sales and flea markets. i pick up small baby toys, plastic figurines, cat toys etc, even a toilet paper roll can be made into a toy. there are websites to show you how to make your own toys, so toys do not have to be a big expense.
cages can be had very reasonably if you buy used ones. there are a lot of them out there, and check Ebay too. i found mine on Craigslist. cages are one of those things you pay an arm and a leg for new, but are very cheap if you go second hand.
my sennie was $500 at a pet store, her cage was $50 (used) and she has a nice second cage i got on line from foster&smith for $70. she has all the room she needs and she is out most of the day.
you should be ok with the $$ you have.
good luck in your quest and let us know what you find
