I have a Viking 6430 that I purchased 30 years ago...If you liked the Viking over the others, that's what you should go with. Make a list of the pros and cons... does it perform the way you want it to? Is it in the price range you have budgeted. These are just two of the many questions that you need to ask. I'd test drive it several times before making that final decision. You may even take a small sample of your quilting and test it. Good luck
