I just bought a thickness planer and realised that I need a dust collector to use it properly. It's not in the budget and so really want to get one at a reasonable price. Is there a CFM minimum that I should consider? Any brand better than another? My local CL has a Jet 3/4hp dust collector. 650 cfm, 120v 4" Dia. hose listed for $125 obo. This sounds small, but maybe it is ok??? Any thoughts or advice?
