Am I too late?This passed 11/16 unlike the other 3 threads so I'll give it a shot.
All About Cockatoos - MyToos.com this,would be a good read.
I've had U2s,M2(Moluccan/Salmon-crested)s and G2(Goffin)s.G2 Star was an expert at lock breaking,M2 Johnson was a rescue and I've had U2 Umbrella for years(close to a decade).They passsed from a tragic fire...
And the dust question-New and Old Worlds don't mix.The Old Worlds (specifically the Greys and Too's) will kill the New Worlds in the long run because of their dust.And no non-stick/telfon stuff either,toxic when heated to birds.
Back to main topic,the link provided will introduce you to a M2's scream,don't get me wrong,U2s could easily surpass that limit.Will your neighbours care even if you don't?They will bite/pluck/mutilate when not given the right care ( and chances are you won't know what the issue is) .Would you want that to happen?They will bite you and others too,hard ones WILL get you to the ER,I've heard stories of people losing an eye or their looks due to a single Too'.

@cassiesdad 's quote
...it's like I always tell people..."Cockatoos have the intelligence of a five year old...the temperament of a two year old....with a can opener on their face...for fifty years."
you can see how Too's work.
If you get a rescue,chances are they might be plucking/mutilating or starting to show that behaviour due to new surroundings.If you choose a young Too' (I am unsure but I'll assume you'll get one older than 1 but no younger than 2 because any older would be unideal for breeders/shops and any younger would be bird mills and you probably never hand fed birds before,not to mention such a big one),behaviour issues/Terrible 2 will come into your life.
Not saying that they are "bad" creatures (They are magnificent and gorgeous) and to prove that I'll show some pics.(and the U2 plucks ps)
Also,quick tip,for gender you could (works 80%) look at eye colour.Amoy is female (laid eggs) (brownish/redish eyes) and Molly is male(probably no dna) (dark brown to almost black) and I just call him Molly because I'm used to that name.
Also,for females chronic egg-laying (and co) is a big issue too (basically laying lots of eggs etc but I'm no expert at this area).I've never had one with egg issues but I swear that it is bad.
I could go on with more Too' details if you ask,but I think that digesting this bit would be good for now.(and 1 last point,they do floor attacks!Ain't much blood since I gave bite victim a bandage in time but you get the hang of it.
