I am totally biased, but I was in your situation 2-3 years ago, and ended up being happy owner of a Kurzweil PC3 76, if I had known better I would have tried to source the PC3K 76, which also can handle user samples, as it opens up for a quite a bit wider palette, not that the non K has a small pallet, contrary, but still.
I love my PC3 and the keybed is imho the perfect compromise for playing both synth, electromechanical sounds, and piano. A tad too heavy for organ, but I do that on another machine anyway, and as the PC3 is multitimbral on 16 parts it's easy to just jack in another midi board and then BAM you have two "synths".
