I like the Lee case trimming system too.
It depends on what type of shooting and reloading you want to do. For precision match type stuff you may want a lathe type like RCBS and Forster offer, the Lee works for average and higher volume loading but is non adjustable (it only trims to min length), and the Giraud trimmer is the most expensive but is said to be better for doing mass amounts of brass (think AR15-M14 in bulk)
I usually use a Lee Zip trim, Lee shellholder and case length gauge for specific calibre (.308 for example) with the Lee Cutter and Ball grip, and Lee chamfer tool. Lyman flash hole debur tool along with Sinclair Primer pocket uniformer (run in a drill) round out my case prep.
