Yes, I am a 'fan' of the Aquaclear (formerly Hagen, Now Fluval) HOB filters (I have 3 AC70's running right now). They let the hobbyist decide what media to use (All of mine are totally filled with sponge material).
As far as models, I like the AC70 the best because of media capacity. I have an AC 50, but it's back in the box.
The Aquaclear sometimes gets bad press because if/when the tank is drained for a water change, if the inlet tubes aren't removed first, the water will siphon back into the tank and the filter will need too be manually refilled, before working again. There's also the complaint that if there's a power failure, or the filter is unplugged, sometimes it won't restart. This is because gunk gets down in the impeller magnet chamber and gums up the works - this just needs to be serviced/cleaned once a month or so for continued uninterrupted operation.
I don't like cartridge filters as although convenient, the cartridges are a replacement cash cow for manufacturers while bio-sponge lasts nearly forever and a day.
I like the look of the Seachem Tidal for many of it's features, especially the submersible Sicce pump that makes it work and that like the Aquaclear, you choose the media. I don't currently have one, but think my next HOB just might be a Seachem Tidal.
