Hey Don, we have several Thor single needle GC-1541S and double-needle GC-1560 machines. We have been running them for around 3 years now and have had great success with them. We are sewing production on these machines so they are running hard 8 hours a day. We have some Consew machines as well but the Thor has a higher foot lift. The extra lift really helps sew through thick parts of a seat cover that have a "J" clip sewn on as well. Hope this helps. Thanks! Brian Verhalen The Seat Shop.

Thanks Brian helped a lot! Thanks again Don.
