VIBRATORY TUMBLER MEDIA??

I've been looking at vibratory cleaners and it seems there are two classes, cheap junk and expensive commercial units. What kind of luck have you had with the durability of the Lyman units? (sorry for hijacking this thread a bit).
I too reload extensively but in answer to OPs original question, I agree with most all. Corn cob for delicate and SST pins for rough stuff. With regard to Lyman tumblers I have had good luck. I now use a Dillion and I like it better. Not because it does a better job but just because it is quieter. Lyman is relegated to backup.
