can anyone recommend me a small or medium sandblasting cabinet that is not too expensive

Look herehttp://www.tptools.com/Default.aspx
I have a 780 in my shop that I use with glass beads and a larger Cleco
cabinent to use with alox

Went to their web site.
And found this warning -
"We do not recommend the use of silica or any type of sand in our abrasive blaster
cabinets."

That's kind of strange warning for a sandblast cabinet or I am missing something here.

The Liability Lawyers insist they put the warning there, because
silicosis from abrasive dusts is bad. And silica sand is not the best
choice for media in a cabinet blasting or production uses - the one
thing it's good for is in a water blaster where high pressure water is
the carrier and the sand is one-use through the gun.

Great for graffiti removal where you'll hose away and/or sweep up
and throw away the sand, and you need cheap media. And everyone
working with it still wears a respirator just in case.

For really delicate work you want baking soda, CO2 dry ice crystals
(special equipment) or ground walnut shell media.

For paint removal and light rust cleaning you want glass beads.
That's all I have at home, and it cleans up rust and loose paint on
metal nicely without removing lots of metal - gives a nice burnished
finish for painting.

For more aggressive cleaning and derusting you use "Black Beauty"
coal slag, crushed glass, or aluminum oxide.

Those who have suffered and died from silicosis would want the warning
also....nasty condition.

Serious health problems from dust are real....as many older
woodworkers can now attest.

Wearing a respirator even with using a cabinet is a smart thing to do.
