I am located in Iceland but I´ll be buying it in Florida (It is 2/3 cheaper in Florida then at home

).
And I think (correct me if I´m wrong) That you thought that I was meaning the diffrence between those and the casio, but I mean the diffrence between tyros 1&2.
I have a piano so I´m not looking for that, but I´d like it to sound like one. It can be 61 keys but I´d prefer it to be larger. I don´t have to carry it around, I´m planning to keep it at home and play with it there. And Lastly my price limit is around $3500
Oh and I have one more question. There is a big price difference between Tyros 1&2. Does it pay? to get Tyros 2 I mean.
Thanks for all your help
