Charleen,
I love my machine, the only thing I really would have liked to have is a stitch regulator, and a thread cutter.
My repair shop is a H. Viking so they know the machines inside out.
I took lessons when I bought the machine at Joanns but you forget most of it if you dont use it often.
There is another forum entry about the 830 and someone gave a website with videos of what to do with it and I downloaded them. It wasnt but last week sometime that it was posted.
