I had three of A2000 versions at some point, two of them dead. I killed one when I inserted it the other way around to the connector, one of the PALs got busted. funny the other broken one had the same PAL busted, seems like a common mistake with those ARs. It's not that rare, but you gotta know where you're watching (nihehe). A1200 one is a totally another class of rarity, class of flying serpents. Usefulness is another issue, hrtmon seems to do just about anything AR does, but if you're Toni Wilen or something you may find a use for it.
