I'm happy with my large, 25 year old Craftsman shop vac and hope it continues to run for 25 more years. Its great for sucking up massive amounts of dust and dirt, but its not really designed to connect to portable power tools. I really want to get high quality vac with auto-start for that job. It'll be mostly sucking up very fine sawdust from the orbital sander, spindle sander, or 4" belt sander. I'm looking at the Fein Turbo I and wonder if the ~5 gallon capacity will be a hinderance. I like the idea of using a replaceable felt bag instead of replacing the filter.
