Maybe some, but I think all the carpets are coming from Germany. Most of the carpet manufactures are in Europe. I bought my carpets from GAHH, only because they allowed e to order the leather bindings. Most all of the other carpet kits from World, Buds, etc. are going to come with vinyl bindings. Prices vary because of the labor. GAHH and World both cut the carpets, Buds gets the kits from a supplier. GAHH is the most expensive because their carpets are cut be a computer cutter, and then hand stitched. It's all about what your taste is and what you want to spend. They are all going to look good. Call/write each one and ask for samples. They will gladly furnish you with samples, then compare.
