I have the 830 and absolutely love it. There are so many features on this machine - I bought it without test driving it - the shop kept calling to tell me about the machine and I wouldn't call them back, my husband asked why. Told him I wanted that machine really bad. His response was "well then get it" It didn't matter the cost. It was in my sewing room the next afternoon. No regrets at all. My machine likes to be used - he works best when he gets a workout every day. You would really like the 820. It will do everything you ever wanted to do!
