From Bob - Woodcraft Sawstop dealer: "The order is still a week or so out, so you can make up your mind later. I sell equal numbers of 1.75 and 3hp PCS, and both customers are happy. If I had full breaker box issues like you, I'd pick the 1.75 in a heartbeat and save the money. And we have the 5hp Clearvue Cyclone here at the school, they are nice but way overkill for a garage shop. I'd look at a 1.5hp Jet dust collector."
From Aaron -
Airpro: "Garage shop and 4" saw air port? I'd get a throwaway shop vac from Home Depot. If you really want a cyclone, then get this Cincinnati fan with a 1/2hp motor, sized 400 CFM for that saw."
