Good luck. I do not think that the 2211 is even availible anymore, at least it is not listed on the Eheim website. If anyone has it it would probably be something that has been sitting on a shelf for a while. Hope I a wrong, would be a great filter for some of the smaller tanks that have been becoming popular.
They still sell them in Australia and Japan. If you have a buddy over there, they can buy one pretty cheap off amazon and ship it but it will end up costing you a pretty penny. Good luck finding one in the states. They occasionally pop up on ebay as well.
