Just saw that the new low voltage controllable Hydor Koralia's are out (saw an announcement somewhere and then saw that Dr. F&S has then online now). The pumps seem to be about the same price as the old Koralia, but the controller is a bit on the high side, a 2 pump controller is around $320. Kit with a pair of 4's and a controller is around $450. Can get the Tunze on a singlecontroller or Vortec for that price... I doubt I'll be jumping out there right away myself to get one, don't have that much lying around right now.
