Thanx guys, i'm pretty pleased. I paid $700AU.
I was in the process of looking at a broken one near me. The guy wanted $395AU and it didn't have the base.
The seller explained some of the history of the machine, it came out of a boot maker that specialised in Orthotics. Long story short, this is about the only tool left in his shop after he had a medical mishap. The family had to dump most of the other tools including sewing machines and Shoe Trees and Sole sewers.
I was also told to buy a couple of presser feet and cut one foot off either side. This is very useful for making orthotics, because it enable you to sew very close to transision.
Now I need to learn how to use it well. I already have several products in mind that will be good on this one.
