I don't think HOB's are junk. If your speaking from just a mechanical standpoint- Whisper, Aqueon, and Marineland make an economical product that functions well. We're talking like $25-$35. If it runs silently for two years then you got your money's worth. Then You can decide to throw it away or buy a new impeller assembly. We live in a disposable society and everything we buy is cheap junk made overseas you can't expect something that costs $30 to last a decade. I agree media and cartridges are ludicrous, but thats your own fault for not cutting squares of poly pads for next to nothing. I did it with my Aqueon filters and when I run out of whisper cartridges I'll wrap quilt poly padding aroubd the black plastic insert and jam it back inside the filter
Compare that to the cost of a namebrand canister...
