Brian,

I second that.  Years ago, my guess is late 80s or early 90s there was a
company, Savings by Design, Inc., that was 
selling a cardboard blast cabinet.  I
used that for several years until Harbor Freight 
came out with a plastic table top
one.  Used those 2, the cardboard and plastic 
one, for many years and at least 2
cars.  Then a friend gave me a nice one on rollers.

I also bought a Harbor Freight pressure blaster.  Used that in the corner of my
back yard.  Tied a piece of rope across the "L" 
in one corner, hung a heavy plastic
sheet acoss the rope with clothes pins.  So I had 
a nice "L" with the plastic, vertical
and then on the ground.  That way I could recover about 90 - 95% of the sand.
I used a piece of screen over a funnel as I 
scooped up the sand and refilled the
pressure blaster.

Check out the article I wrote on how I did it:

I mention the cardboard cabinet in this article, about 1/2 way down:

It's a shame that they still aren't available.  I 
don't know why they company quite selling them 
and folded, but my guess is the  plastic ones just got to competative
in price.

One note on using a Shop vac to evacuate the dust from the cabinet.  Put a
couple of inches of water in the bottom of the vac.  This will help keep from
clogging the filter so quickly.
