Thanks Kaley.
I have purchased a couple of new keys since.
A Yamaha and a Casio that is a little fancier and has eq features on them. A Casio-500 and a Yamaha PSS-470.
The piano still does'nt sound as real to me on those 2 new keyboards.
John Lennon's "Imagine" kind of sticks in my head when I am trying out the piano sound.
And only my Casio CTK-411 has come close to that piano in that song.
