Great advice from SB! It is great that you are doing your homework. Toos definitely require a special kind of owner. Recommended that they have big bird or Too experience. They can be very demanding, very loud, very destructive and very expensive in way of upkeep. That being said, Toos can be loving snuggle bunnies, playful, fun and true companions. Each bird is an individual.
If you live in an apartment, do not get a Too. You will be asked to leave. Citrons are truly beautiful birds. Not to big or small. Not as clingy as the bigger Toos. They don't talk real great, but most Toos are not know for being great talkers. SC2s are active birds, big chewers that need lots of toys to destroy. They require a large cage. They need to be kept entertained, either by you, foraging toys and other toys. It is important they learn to play by themselves. If they become stressed or bored it can lead to screaming, feather plucking and mutilation. This applies to all parrots.
I recommend you find a rescue or sanctuary in your area to visit. There will be lots of Toos there. They are frequently rehomed. You can then learn all about Toos by visiting, talking with personnel, and actually be exposed to the bird.
I am not trying to turn you off, just want you to be prepared.
