If the rumors about o.s. 3 for PA-80 are true I would recomend that but if you can wait till january 2001 I would sujest you to do so winter NAMM will bring newer keyboards and newer o.s. for many keyboards but if you are in a hurry I will sugest that download the manuals for both keyboards (2000 and PA-80) and compare them keeping your needs in mind.
