I have just gotten a rose breasted Cockatoo about a 1 1/2 mos. ago maybe 2 not sure. He is a hoot! He has a HUGE personality!! He is fully flighted and is right now circling the house! He plays literally plays with my dogs. I have a small Chinese crested and a Chihuahua. Nigel Thinks they are part of his flock. When sun shines onto the floor through the window you will find all three of them grouped together "sunning". My little Chinese crested (Pia) which is so happy to find that Nigel would like to hang with her will jump on a chair, Nigel will fly on the chair, Pia jumps on the floor, Nigel flies to the floor and on and on it goes.
He will fly over to me, beg a little for attention and then off he goes to play. I think you would love an rb2. Yes the price here in the states is high (1500) but then remember that birds that are so much cheaper here are sooo expensive overseas. I am not sure where you are located but my breeder has two girls that are Nigels clutchmates as well as a male that is a bit older. It would give you the opportunity to meet some. They also have a couple of older birds that are always loose in the aviary (weather permitting) Again, I am in Ohio and not sure where you are.
I would also advise against any of the big white 2's. They in my opinion are not birds that do well in most home environments. In fact even in the best circumstances they are difficult. Not to mention LOUD, I mean really, really Loud!!!
