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.
Thanks, Ralph
