I have an older Viking Platinum 770. Actually just picked up a walking foot for it a couple of hours ago. I love this machine. I've had zero issues with it; have only taken it in occasionally for service (it does need a good cleaning right now but no down time for a bit).
When I bought the machine I did a spreadsheet of my must haves vs wants and looked at many different brands. I read lots of reviews. The viking won without question. Particularly when I factored in cost and getting lots of bells & whistles I didn't particularly want.
The deciding factor for me - in your position - would be the fact that the Viking dealer is so close to you. I've had great support from my dealer. And that is something that definitely has a value. Just make sure you and the dealer (or at least the repair guy there) have rapport.
