I am looking to upgrade from a Korg i3. I've looked at Yamaha 9000 Pro and Korg PA80 and have read the various postings comparing these two arranger keyboards. Still can't decide. I use the arranger keyboard when composing contemporary songs - pop, blues and country and would like to get away from the "cheesy" dated styles on the i3. Would the Korg PA80 meet my needs? Any advice would be appreciated!
