I couldn't agree more about the price.., but in Yammie's defense I have this issue with all the upper end arrangers. There's absolutely nothing IMO that sets these arrangers apart from workstation's in terms of their application for the player.

Arranger players scream more styles, workstation players scream more arps.., but the price difference is major. Yet the pro arranger is often built of lower quality than the pro workstation, but the price sure doesn't reflect that.
