Yup agree 100% Rodney.. There is not enough money or flexablity available in putting out the bucks for a machine specifically for marking metal. The fibermark from epilog seems like a nice machine, but the only people I have seen buying it as yet, are industrial users that need it to mark 'their' products and parts, and their not usually interested in doing outside work.. I think I lucked out on this tube replacement, and the tube was the only thing replaced.. Had to do a very minor tweak on the alignment, and replaced one mirror. I was told the tube Epilog sent, was the correct one, matched to their records for the Ser# of machine I have.. These tags I'm marking have a very small area, (.25" x 1") so even at a speed of 2-3% @ 600 dpi for extra overlap and 'burn in', they still go pretty quick if their set up in vertical columns to keep down the head travel..
