When did Ridgid discontinue these and were they any good?
I might have an opportunity to buy one, and I only use one tool at a time
but my shop vac doesn't keep up very well. I have been considering an
Oneida Dust Deputy but, there again, I suspect that if the shop vac isn't
keeping up with the tool, the cyclone won't improve it, only save me from
emptying the vac as often.
