Best cannister filters and why?

I use an Eheim 2215 with sera siporax as biomedia. It works great for me.
 
Love my fluval. Great bang for the buck. I don't think it is hard at all to maintain and it is the most quiet filter I have ever run on any of my tanks. It has a good deal of room for different media types and the media for it isn't that expensive. The only problem I have with it is sometimes it is a little tempremental to prime, but all in all a wonderful product.
 
Just to close the loop here on one particular point. Although RTR prefers Eheims, his recommended media work well in Fluvals as well. I use ceramic noodles on the bottom and then bioballs in the rest of the canister.
 
Rena Filstar XP models....

When the time comes to get rid of my Fluval 404, it will be replaced with a Filstar XP3. There's more options with Filstar canisters - especially control of water flow and the options on setting it up. It's a great filter and it's priced right! :)
 
Anyone else like the Filstars? Right now I think I will order a couple Fluval 304s. I would like more info on the Filstars first.
I plan to put two 304s on a 100-120gal setup,but not sure yet.
 
I just purchased a Filstar XP2 for my 55g community tank and really enjoy it. It's my first cannister filter, and I don't have much experience with cannister filters, but a few features really impressed me:
First off, this filter is nearly silent. There's a hum when I have the stand's cabinet open and that's it.
Secondly, the number of different set-up options out of the box are pretty impressive. The inlet fittings allow you to run the inlet pipe all the way to the gravel if you like, or just below the surface, while the outlet pipe has fittings for a spraybar (settings for horizontal or vertical spraybars) venturi, and a powerhead-style nozzle attachment for more current.
Finally, this filter is really easy to maintain. (Yeah, I just got it, but shortly after it was all set up, I decided that I wanted to tweak the media a little... Doh!) Just unplugged it, popped the hoses off (includes a sort of switch that keeps water in the tubing... no broken siphon or water everywhere) and took the cannister to the bathtub.
All in all, I think it's a pretty sweet piece of equipment. At $70 plus shipping from Big Al's, I thought it was a pretty good deal (media's included).
 
eheim eheim eheim! they are the most reliable canister filters on the market, they also live forevor a good friend of mine has had one running for 13 years now (with proper matinence of course) without any problems, except maybe replacing o-rings and such things.
 
IMO- you can't beat Filstars. From a design point-of-view, they are very similar to the Eheim Pro series, and they don't finacially rape you like Eheim does. I've been running mine for well over a year and so far, I see no difference in form or function from the overpriced Eheims. I'll never buy another brand's canister again.
