Chris, I've been using a Delta 50-179 for about 16 years now. 3/4 hp, 550 cfm, two stage. Many of the others, even much more expensive ones, are single stage, where everything goes thru the fan. This one goes thru a barrel with a deflector that drops all the big stuff in the barrel, then the fine stuff goes thru the fan and into the bag. I don't know if they still make the same model, but I know I recently saw a similar one, and also a seperate lid for a standard garbage can that does the two stage thing for any dust collector. The 550 cfm works great on my radial arm saw, router table, planer, and molder. It works fairly well on the table saw, but that has too many openings for the adjustment controls to pull enough air thru the blade opening to pick up everything. It does pick up the fine stuff, which is most important. HTH and see ya at Winterfest :cheers:
