I finally wore out the cheaper Lyman trimmer after about 30 years of usage. I bought the top of the line Orange Lyman a few years ago. This is the one with the universal style shell holder. I also got the shaft that you can attach a power drill etc. to turn it. Once set I can trim a bunch of cases in no time. I just use a RCBS chamfer tool by hand.
One trick that I do to save wear on the shaft to frame surface is to support my drill that I attach to power the shaft. I mounted my trimmer on a piece of 1/2" composite decking board that I can C-clamp to my loading bench. I use an old electric variable speed drill to power it. To support the weight of the drill and keep from putting downward pressure all the time on the shaft. I can lay the drill on it's relatively flat side with handle and trigger facing me on top of a piece of 2x4 wood with a plastic tray that comes out of a box of 9mm ammo on top of the wood. This supports the weight of the drill and also allows the two plastic surfaces to slide on each other for smooth operation. I use my thumb to operate the trigger on the drill.
