I have an old 830 and I wouldn't trade it in for anything. It just won't stop. I made my daughter's wedding dress on it and I have repaired leather straps on my sandals with it. See if you can get a manual for it. It will help. I've sewed huge sails for a sail boat, a horse blanket on it. Get it cleaned up and you will enjoy it. I understand that there was a flood at the factory and you can't get new parts for it, but usually the dealer has some extras from trade-ins. Also, you can get parts or at least feet for it on the internet. I have a 440 QE and I love the new features that it has, but it seems that whenever I decide to go on a retreat, it has problems and I end up taking the 830.
