I haven't tried the Lyman version, but I can tell you that the vertical orientation of the tools, like the RCBS case prep center I had, got tiring after a while. It's a bit hard on the wrists. Still better than doing it all by hand though. But not nearly as good as the horizontal (front mounted) tools on my new Hornady case prep center. Of course, it costs double. If you count the cost of a quality case trimmer, and the case prep center it works out pretty close to each other.
Just my 2cents. Hope it helps.
