I have the Roland Fantom S88 , which is last years model of the fantom X. I like this keyboard very much. She will like it also. The Roland
has better piano sounds than the Korg Triton. I had the Triton Pro X
88. I just sold that and bought the Korg Triton Extreme which I like
very well with all the expansion boards that are already included.
The Piano action is good on the Roland X also. Tht new model of the
Roland X is not much different than the Fantom S. Just more memory
and more sounds and those sort of things.
