Used Equipment

As we put in new equipment and remove older systems, we sometimes acquire used equipment or agree to help our customers sell their old equipment. 

Only equipment known to be in working condition will be listed here.  All equipment is sold "as is".

No warranties are offered or implied.

We currently have used items (and some new spares) listed for sale from the manufacturers listed below.   Click on the manufacturer to see the current list.
