I`ve had a problem with polyphony on my K2000s. While it`s a little different type of polyphony than most keyboards (the oscillators don`t take up voices, just samples, excepr 1 per midi channel). I`ve still had a good portion of clipping. The reason I`d get this is for the strings. The Orchestral expansion ROM is just amazing as well!!! Plus you can pick one up new for about $1200, with the sampling option. It`s defintely worth the money, but only if you use it in conjunction with other synths.
