I put bags in the UDD. Just regular trash bags and they literally take seconds to replace. I'll never have to replace my filter in my ac36, and my ct bag lasts forever as nothing even gets to it. The UDD fits on top of the vac and being made for a ct is just the best thing I could imagine if you're looking for a cyclone. Is $250 too much for this setup, not at all IMO. I agree if you do drywall ever this thing is a must, or another dust deputy type. If the UDD were a piece of junk and just not worth buying, I wouldn't be singing its praises. If I were dissappointed, I would definitely voice that opinion. But this thing has been one of the best things I've put into my shop. Not to mention I use a drop hose from my ceiling and the udd gets the hose a lot higher off the ground so there's more useable hose to move around my 4'x8 work table.
