I've got an Artograph 1520 booth, and judging from the pictures they're basically the same thing, so here goes:
Fan is decently quiet (I'd say it's barely quieter than my vacuum cleaner and about the same as my stove's range hood on high).
I like the fact it's got the filters because my situation doesn't exactly lend itself to outside venting. That being said, I've only used enamels and acrylics in it, and am considering limiting myself to acrylics in the future as long as I'm not venting outside (the filters work pretty well... there's a vent on the back, and I have yet to find any paint build up on the wall behind it). I would not consider using lacquers due to lack of outside venting, but that's sort of a situational thing... if I were able to vent it outside, I'd give it some thought.
I wouldn't recommend using it with spray cans or airbrushes spraying at full power.
Size is decent. A 1/48 F-15 was sort of a tight fit; 1/48 WWII fighters, 1/35 armor, and 1/25 autos haven't been a problem.
I bought it as an Artograph, which came with a cardboard hood, and then purchased the metal hood separately... it turned out to be cheaper that way at the time (~5 years ago). The microlux unit looks like the metal hood is standard. I believe Testors sells this same unit, too.
