I've got a 2224, I believe it's an older model though, it's not as fancy looking as this one. It's the pro series though. I love it. It's small, quiet, and does a good job. Granted, it's rated for a 60g tank, but I won't use it on anything bigger than a 29 (used it on a 10 for some time). The eheim pro series is very expensive, that definitely sounds like a good deal.
"What, exactly, is the internet? Basically it is a global network exchanging digitized data in such a way that any computer, anywhere, that is equipped with a device called a 'modem', can make a noise like a duck choking on a kazoo." - Dave Barry
