Group buy of DC1100 particle counter (link included)
 

Particle counters are used to test air quality. I found an inexpensive
one that is ideal for your workshop. I started a thread about it at
woodnet and sawmillcreek, and the response was pretty enthusiastic.
This led to me negotiating a group purchase of the units, where we
will get an additional 35% off.

If you want one of these, this is the order form you have to download,
fill out, and fax to Dylos:
