I have both...besides the difference in cost. I'm pleased with both filters.
To me it's which one fits your current budget......FX5 was around 60.00 less than the 2260.
I've had the FX 5 almost 2 years, the 2260 going on 1.
The eheim is a monster in as far as capacity, it's old school but highly effective.
i have the fx5 and i like it.. it pretty easy to set up.. but i dink the 2262 is more expensive.. hahaha.. good luck with ur choice.. both are good though..
i have an fx5. it's my first cannister. i like my fx5. it does a great job. both fluval and eheim are eurpoean companies. they are like european cars. built to last and run. you can't go wrong with either.
