I have the JDS 8-12 (similar unit, just a little larger). It's a nice to have in the shop and does a great job of circulating, and filtering, the air. Mine doesn't have the fancy remote, but does have two speeds (though I've never changed the speed since I bought it, it's always on "high"). I would recommend it.
Tip - Keep and eye on CraigsList. I've seen a couple in the past few months on there. I bought mine used in nearly new condition for $225.
