Blowers that Attach to the Walls

I've been tossing the idea around about getting a blower that attachs to the wall. I know Oster makes one that accomodates 2 people using it at once, and Hanvey has one that accomodates one person. Has anyone had any experience with a blower like this, can you make any reccomendations?

I have seen all kinds of dryers mounted on the walls. K9's, Metros strapped on a little shelf, Double K's. I think as long as you make it easy to clean the filter it should be fine.
