Elite Hush HOB

Never used them, but I know they are lower in quality than say an aquaclear. I'm sure it will move enough water, but i would be more concerned with longevity. I would also forego the use of their filter cartridges in favor of some reusable sponges cut to fit in the media compartment (kind of a weird shape in the hush filter if I remember)
 
I don't like the AquaClears as the media filled while I was at school one day and the water overflowed the back of the filter and caused a huge water mess in my room. What about Penguin BIO-Wheel 150 or 170? I have read that they start out with the BIO-Wheel moving steady, but then they stagger and stop as bacteria builds. How long does this take??
