I finally got the machine of my dreams, a Viking 6430, from eBay. It was complete and recently serviced. It has a larger throat area and the light source is in the throat area and provides lots of light. I searched a long time for just the right 6430. I made an offer, it was accepted, it was less than $200 including shipping. There are some great deals on eBay, you just have to decide what you want and check frequently.
