I bought a banner welder from Supply 55 and that thing works awesome!! Almost just like a big shrink wrap sealer. I had 100 double sided pole pocket banners to do, so it paid for itself on that one job. It is only 24" wide, so can get a little cumbersome, but I have done 5' by 50' banners on it and probably only took 10 minutes to weld. I would recommend it to anyone looking at one.
