If you like embroidery, get the 830 (if you can afford it) the 820 does not do embroidery. I did something similar & I'm happy that I did. I first bought an 830. I'd also been looking at a Pfaff Creative Vision. I knew I wouldn't be satisfied unless I got one, so I spent the bucks & got the CV. I'm happy with that decision. Each machine does things a bit different, the embroidery hoops on the CV are larger than on the 830, but the 830 is a work horse itself & does marvelous things. My point is this, if the 820 will make you truly happy, get one. I'm completely happy with my decision to get both machines. I have no need now to upgrade to any other machine, I think I have the best of both worlds. Good luck.
