You should check out Sonicstate's Gas Station and take a look at the Kurzweil discussion there - it's filled with complaints about lemons, piss-poor technical support from trhe manufacturer, etc. Personally, I just recommended a K2KVP to a friend over a XP-60, because of the way it can import samples even without the sampling option installed. The effects are weaker than on newer units, but in terms of flexibility and power it can't be beaten in my book - except for the K2500! Dependability has never been an issue for me with them, so perhaps it just depends on whether you get a lemon or not... Good luck making your decision.
