Bead Blasting Follow-up question

Help -
There was what I think was a recent discussion (or at least mention) of 
bead blasting cabinets, where someone mentioned Harbor Freight Salvage as a 
possible source of an inexpensive unit.  I have been unable to find that 
discussion.  My question though is for anyone who uses this process.  The 
manual seems to strongly emphasize respiratory precautions.  Is this, in 
fact, a real concern, even with these smaller units? Also, what's the best 
material for cleaning action parts and screws?

Many thanks -
