I jumped on the HD2 bandwagon when they first came out too. Being in aus, i think mine costme somewhere around $80-$90. It is a better filter than the HD, and i find it easy to clean.
Mine didn't last very long though. The glue that holds the pleated (paper?) onto the plastic rings let go, so the pleating isn't sealing and is free to just wave around. It only took a few months. I've never been hard on them, just a light tap and a blow out with air like I do to all my filters. I ended up going back to the HD which while not as good of a filter does seem a lot more durable. Maybe I just got a bad one, but at those prices I'm not that keen to repeat the experiment.
