I'm looking at purchasing a wet/dry vacuum. I've been chatting with a couple of other members here regarding brands, features, etc. Anyone here have any good or bad experiences, any recommendations? Keep in mind that I'm in Canada, so some brands may not be available here. I've heard some good things about Craftsman, but I know that Sears is having problems, and may not be around much longer. Is the ShopVac brand the best? Thanks in advance.
