There is a really nice piano in the Poser 5 content CD. It's available with Poser 5 and you can download it with Poser 6. Not sure if it's available as a download with Poser 7 though.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
