while shopping at my local home depot today, i came across a "dust collection" set by ridgid for about 79.00. it claimed to be enough to hook up 3 tools i believe and be used with either a dust collector or a shop vac. as i am limited by space and currently only own a table saw and jointer (both ridgid) for shop tools, i would use my shop vac. is this worth the money? is it effective? or should i just continue using my shop vac to clean up after myself?
