I had the E50 and it is a great board. The keybed is good, but I personally think the 3000 is equal to it.
Of course, my training is from the organ route, so these type boards suit me fine.
I do tons of uptempo, modern and rock oriented stuff - trust me, the 3000 rocks when you want it to. It's all in your creativity and imagination
There is not a job that goes by in which a group of patrons come up and want to know how I get so much music out of the 3000. I simply love the board and its fabulous, easily navigable features for live play.
Good luck on whatever you choose.
