I have returned from an evening of checking out a few stores locally. I checked PetSmart, PetCo, and 2 LPSs and not one place had the hanger. I looked at the link provided, but ain't no way I'm paying nearly $8 for a $4 item. I looked at the other items in the link, but didn't find anything I was interested in. I may have to DIY something. Bah.
The filter is working fine. I haven't used it long enough to say that I'd recommend it. I'd need at least a month, but so far, so good. It was quick and easy to set up, it basically disappears in the tank, it's quiet, and I was able to stuff alot of filter media into it.
