I've got a V-5000 that has a plastic blower housing & cyclone. The gaskets haven't been a problem, but those J-bolts that hold on the filter are a pain. I hate them. The plastic is quieter though, so there is that. Another thing I don't like is the super stiff flex that connects the bottom of the cyclone to the drum. Makes emptying a chore. So, some good, some bad.
