I'll bet there are only a very few manufacturers that make most or all of the tumblers that are sold under many names. I've had the big Dillon Model for about thirty years and it works fine. I used a small Midway a lot for about twenty years and it quit. Bought another small Midway and I expect it to last a long time. And that's coming from someone who generally avoids Midway-branded stuff because of its lesser quality.
