I believe the substantially higher price of arrangers vs workstions has everything to do with far fewer arranger units produced and sold than workstations. If arrangers became more popular than workstations, arranger prices would drop below workstations. On the otherhand, If manufacterers decide to integrate comprehensive arranger features into their workstations, they'd want to jack up their workstation prices, which would piss off the larger workstation crowd who don't give a hoot about auto accomp features. Is there anything that will keep everyone happy? hmm.
