To me the psr2000 fits perfectly. I had a lot problems in 740 using touch response. No matter how much I trained, it never sounded good. Allways one note here and there came out louder or were very quiet. So eventually I played without it.
But when playing a real piano, no problems. And in psr2000, no problems.
Key feel is in my opinion very good, or at least much better than in 740. It�s not a piano but good enough!
