Ed sent my Juki TL98Q to me while I was in Germany. He is fabulous to work with and very helpful. There were no problems in shipping nor have I ever had a problem with mine. This is really a workhorse of a machine. They are a mechanical straight stitch machine (at least mine is) and very user friendly. I'm not sure which one you're looking for but Ed certainly would help you anyway he could.
I'm not sure why they are not more available though dealers in our towns/cities. Maybe Juki just wants specific dealers to sell their machines. Juki was headquartered in Florida somewhere (can't remember at this moment the town) but you could google them and call for any information you might need.
