I have several Eheim Classics (though they are not really Classics as I bought them before they were classics - if you know what I mean) and one Eheim Pro (not a Pro II). The Pro is slightly quieter and certainly easier to maintain with its built in taps and quick release connectors. The main problem I find with external filters is sympathetic resonances with the aquarium cabinet causing a faint hummmm.
I found Aquatics Wharehouse to be cheapest though they sent me the wrong filter first time round - they swapped two digits in the model number.
