I have a newer Ridgid that replaced an older one. The newer one is a little less noisy, but the more important factors for me were a) budget and b) filtering.
The big thing that lead me to the new Ridgid was their availability of filters and bags. When equipped with both the HEPA filter and bag, they're supposedly OSHA compliant or some such. Regardless, my lungs feel a hell of a lot better, now. (I do use it with a bucket separator, too).
