It appears that this machine is an industrial type machine and can sew through leather and at a fairly high speed. Someone listed one for sale back in 2011 for $2000 but I do not know if it actually sold. On ebay one sold for 300 pounds (is that about $450 maybe?). Not sure why the prices are all over the place but maybe due to excellent shape and extras, it is a good deal? That would of course depend on what you want to use it for and how badly you want it. Anyway, if you google it you will find some information on the machine. I hope others who know so much more will respond to you posting.
