Scott,
I thought you were about to sell your KN 5000...
Frank, do you still have the VA 7 you bought from Uncle Dave besides the PA 80 you bought from DonM?
In this case I would say that you are more than strong in the style department and I would go for the 9000 Pro, for its ease of use, quality of sounds and reliability; if you, on the other hand, made the BIG mistake of selling your VA 7, then I would go for the SD1, for the quality of its styles. In either case, I would say that you don't need the PA 80.
Not very diplomatic, maybe, but that's just my opinion...
