We started with a Diage III quickmount, had to use a sled, very awkward as we finally used 1/4 plex, once we got the hang of it (after a lot of ruined prints) did ok with it. We just recently upgraded to the GBC Titan and like it a lot, and have the tech here tomorrow to check it over and "train" us. Have been using it for a month now. We also have Dale's big squeege's that we use for some things but have not tried to laminate. Last ramble here, do a search and you will find a number of threads with lots of great info, and one has Island Sign who has put out some videos that are great.
good luck,
Hal
