I would say there's more to the specs that cfm and static pressure. You also have to consider how much dust is going to be removed. If it's just a bag type, a lot of dust is going to escape, or the bag will clog easily. A cyclone system seems to be more efficient at removing dust and keeping the filter clean. They do cost more. I guess it depends on what your requirements are.
