I just sewed up one each of a 60" and a 62" dual layer gunbelt. On the Boss. If you're running a high volume production shop, it might not be the way to go, fits in perfectly for me. I'd love to buy a Cobra Class 4, and was debating the one for sale in the classifieds for 2000, but I figure that money can be better spent elsewhere for the time being. Right now I can stitch a bunch of holster or belts on the weekend, then mess around after work for a few hours finishing the batch, then start over again next weekend.
