Four gauges and four MECs.
Started with a MEC 650 12-Ga in 1968 (Nope, MEC didn't send me a 40-year pin last year). Now, I've got Grabbers dating from the late 80's. No juice power assist nor auto-indexing for me (gotta get some exercise for these old bones), but I've up-graded to the larger wooden handles. Pulling the lever and advancing the plate are cheap therapy.
