It's just a rename of the 820, as far as I understand. 15" free arm, but 12" needle to pillar as always. I also got excited, because I happened to look at the website one day when the 820 with the old face plate and the "B 820 Quilter's Edition" were both shown. Dunno if the name is supposed to attract quilters to push non-quilters to the 830. How 'bout a fancy swirly face plate and limited edition stitches like the 830 LE?!
