I just purchased a Grizzley G0513x2 Bandsaw (17") that had two 4" dust ports. It sounds like some kind of suction is necessary to keep the dust down in my two-car garage. My budget is limited. Grizzly has a 1hp Dust Collector for $199 1 HP Dust Collector - Grizzly Industrial. I see some simply use a shop vac. Which of these two choices would you recommend? Is the 1 hp Dust Collector enough to do the job? Will a shop vac be enough to suction from two 4" ports? Or am I best just to use a broom and dustpan after each use? Decisions, decisions....
