Well, I never owned a 3000, but I played one a couple times. Speaking of key feel, I can say that the 900 key feel is much better than the 3000. I hated the 3000 key feel. Always felt like the keys would just snapp off at any moment. Obviously, they never did, but ugg. The 900 doesn't have great keey feel by any means, but much superior to 3000.
