Thanks to you all.
Your answer gives me a lot to work with Glen. I think I stay with the mda piano for a while, and see how close I can come with it.
In mda piano I have some control over the tone. Maybe pianoteg has more controls, but since I am not a pianoplayer at all, I am afraid that there are to many controls, so the result will be a real mess if I start to try them out. All of the answers in this thread was of great value of course, since they made it more easy to figure out what to go for.
But it is always nice to have adwice from one that is spesialist on the instrument that I try to replicate, it make it more easy to zoom in on the real thing, and also stay clear of the biggest pitfalls.

Best regards
