Richard, there is a limited cost and I included that in the baseline.  Most use an integrated vacuum filter system which collects the dust.  This is pretty much standard on all new equipment.  I used a heavy duty, high capacity Shop Vac at my last job to collect the dust from Cencorp 1000 series routers.  It helped that Shop Vac was close by.  If I were needing to jury rig a system again, I would use a Stanley as they are much quieter and are easier to fit the hepa filters.

As far as the contacts that I give, they are persons who have done well by me and that is saying something as I am known to be both intense and demanding.
