Anyone who is paying $5000 for a Tyros4 isn't shopping around. Either is anyone paying $4000. I have already presold my Tyros3 and am only taking a $1100 difference. Calculating the 2 years between the Tyros3 and Tyros4 it's costing me less than $50 a month to upgrade to a Tyros4. That's a lot of bang for my buck! I love my Tyros3 and will love Tyros4 even more. -charley
