Hey Peter,
I got one of the big Lyman Auto Flo vibratory cleaners perhaps fifteen years ago, it is still going strong, and I like it very much for cleaning my cases. Having said that, however, I do not use the media drain feature at all. Like Dick, I find it much easier to pour everything into a big sifter over a big bucket. Works faster that way for me. That does not, however, mean it is not a good case cleaner. It really is a good product. I just do not find that feature useful.
Best wishes,
Dave Wile
