Anyone ever see or use the Oneida dustless vac system?
Iam thinking of getting one. I was told by almost everyone that you can not connect a shop vac directly to a edger or drum sander and get good results.....this system has a filter that filters the dust and then a vac that sucks it out and dumps it into a 35 gallon drum for easy clean up....any thoughts on this?

A big machine hooked to a shop vac..........that creates a hilarious mental image. hoho

The Oneida system is sound engineering from top to bottom. Pricey,though.
