Well if anyone is willing to pay $5000 for a Tyros 4, let me know and I'll buy a as many as you want and sell them to you!
That's not even close to what you can buy them for.
But I agree they are still pretty high.
I can't understand how you can form a real opinion on keyboards that are not even being produced yet, as BK9!
Look at just the specs and hype and Fran's Mediastation is the absolute best!
