I’m looking for a new tumbler and would like to know what’s the difference between the Lyman Turbo 1200 Classic and Lyman Turbo 1200 Pro ? Is the Lyman Tumbler good and which one do you recommend ?

I've had a Lyman 3200 case tumbler for probably 25 years and I have no complaints. I would therefore say Lyman makes a good tumbler.

If you go to the MidwayUSA web site, you can get descriptions of the various tumblers. The information is useful even if you don't buy from them.
