Due to the lack of feedback on here, I called a few places. They said that often times, a high shank and industrial (both screw on types) are one in the same, although some high shanks are meant for zig-zag machines and may not work well. Like the Janome High shank link I listed above....I can get that to work on the Juki, but I have to get the one meant for a straight stitch and not zig-zag machine.
I found this on eBay and called the store in PA. The owner thinks it will work fine on the Juki. Since it's only $14, I think I will give it a try before I screw my $30 Juki foot up! lol
