Eheim 2217 is amazing, but don't ever store a canister filter on its side while wet, ever.
I hear the 2217 doesn't do so hot in the mechanical filter dept, but I have no experience one way or the other. The eheim 2075 pro 3 looks nice, I really want a fluval fx5 though. *drool*
I have friends that are hard-core into racing... I could drop an engine off and pick it up a week later and it'd be fully rebuilt and ready to handle 20 PSI of boost to boot... My friends are all crazy into turbo'ing EVERYTHING.
Yea, expensive preposition. Sounds like fun though!
