At the end of the day you have to spend time going through the detail of any new instrument before you buy. Thank God there are so many good boards out there we are spoiled for choice. The only comment i can make here that has not (as far as i can tell) been said, is that far too often i see what appears to be very minor issues with a brand of performance keyboard becomeing THE reason that it is overlooked. If having 3 fillin or 4 fillins is what tips the scale for you then fine . But dont overlook the other features that could make the world of difference to not just how you currently use arranger keyboards but also how you play.

If you listen to Rod Pooley (well established organist in UK and player of the Korg pa800 you would be hard pressed to see whether the PA series had just two fillins.Then after listening to the these performances ask yourself ' does 2 ,3,4,5, fillins really matter all that much ?'

Just my 2 cents
