This may sound stupid but why not install the gladiator style bins/rack system inside of a cabinet?

I personally have mine out in the open on a wall and they get dust etc but it doesn't bother me. But the cabinet idea would be cheaper and less of an eye sore then the ones you listed in my opinion. Get a used cabinet,Paint it if needed,install bins/racks and your done.
