Nick,
So it sounds like you really did not NEED an arranger. If I didn't want an arranger..I would go right out and but a Kurzweil PC3X...no questions asked...But I play arranger not just synth.

I had a K2600 synth (kick ass for sure) but it was not an arranger...and that's what I need to play the way I want.

I plan to add a M3 to the PA2XPRO...and have the best of both worlds...or, maybe even a Motif XS RACK.
