I'm thinking the pa800 and the E60 are both going to be better than the 3k. but the 3k is lighter by 6 lbs and it's a
fine kb. any good artist can sound good on any of these.
The E60 will have the 76 advantage, and the pa800 will
just have more and better sounds and styles, and probably a much better internal speaker option.

Not an arranger (wish it was) but the yamaha ypg 525 is
a superlight 88 that just blew me away..has great keyfeel,
great live! grand, and a super suitcase Rhodes sound. and
you can buy it for $599, or even $499 at some discounters.
