question about synths

[Jeffery Hildebrand <jshildebrand@ucdavis.edu>]

        i'm getting ready to buy one, maybe two keybaords. i am so far in
favor of the triton, although the novelty has worn off about now, and i'm
also thinking about the yamaha S80 and EX5 or EX5R. i am truly impressed
with the acoustic modeling technology of the EX5, but that's really all
i'd want out of it. i also want a great piano action keyboard, and i don't
know if the S80 is for me because it doesn't have hammer action keys. what
are the most realistic piano-like boards out there? and if you have a
triton, is any of the expansion really necessary?

                        thanks,
                                                scott
