Hey Jim, let me get this straight....... you're looking for a unweighted keyboard that has good pianos, e.p's, organs, and strings. Ok here's my two cents worth, for the 3 you're looking at, I would recommend the XP-80, not only are the sounds of a good quality on the synth itself, but it is also extremely expandable..... so if you don't particularly care for one category of sounds on it, you can buy an expansion board for those sounds. The exp. board collection for the JV/XP series synths is probably the most versatile collection out there.(18 boards in all) And second, it has a sequencer; that can come in handy when trying to think up new music. I just think that you could do better with the Roland than either of the other two. It will keep you busy for a long time.
