Cliff,

While typing my reply, I was thinking of Kurzweil K2600 as well. However, I personally do not accept K2600 as a modern competing keyboard. I strongly believe its time is over and I will not pay for it more than $2000 regardless of how many upgrades it comes with. Nevertheless, you got a point. We cannot deny that K2600 was at one point the best sounding synth ever.
