I like shop type vacuums,too but their are bulky and heavy-can be hard to collect.Guess any vacuum collector should at least have a few.The one WD shop type vacuum I REALLY want is the older ext filter NSS bronco vacuum-it had a polished SS drum and motor housing-the motor suction fan blew into a large,cloth blue bag with the NSS "Horse" logo!!Saw one so many years ago in a commercial vac place want one!!!!NSS replaced that machine with an internal filter Bronco model.The ext filter one was just cooler.
