Seems like I'm stalking Vaughn, but I bought my Jet Air Cleaner at the same time he did from Amazon. I cut a couple 2x4's and mounted them between the floor joist then installed 4 4" carriage bolts down and mounted the cleaner to it. It's very nice and quite.
I didn't have the squirrel cage problem, but I did have a little damage on the filter end. It looks like it was dropped on its edge at one time. I doesn't do anything to the performance and mounted you really cant see it.
Now its time to save up some more money and buy a dc.
