I sent an email. They said 89 cents and they would ship anywhere in US for free. That's a heck of a lot less then I'm spending for J's. I think I am going to try them out and see how it goes. From what I can see they would be a good cost saver for the small runs off of the mains. I don't think I would use them for a heavy bundle.
If anyone out there knows more about them, let me know.
