I have a Juki and love it. I've had it several years and only had one problem. Had a burr on the hook.
Don't know where you live in Florida but there is a dealer in Mt. Dora. It's "Sew Mini Things". They do have a website. I'm sure they would ship to you. Contact Stuart or Timm. They will be glad to help you. If you need a phone number I can get it for you.
