I checked ebay to see if any HOG 2s were listed - they are, at $476 shipped. Some folks have the HOG listed for $509.
Seems the new preset controllers are cheaper than the old one - at new prices. The new ones going for like $130 something IRRC, and the old ones are listed for more.
I wouldn't buy the controller as I'd use my midi controller for presets. Not sure if I want to dish out the $476 either but seems like it could be worth it given the old HOGs may be going for the same or more.
