I had the Ruby before the Deluxe came out and it is such a great easy to use machine. I say "had" because I traded my Ruby in for the Diamond Deluxe. The store had many tradeins at that time and I know that at least for mine; it was sold before I got it in to turn it in. They had long waiting list for them. The Ruby Deluxe has more features than the Ruby. You can see a comparison chart on Vikings website for all of their machines. I love embroidering with the machine, I'm kind of addicted to it. I've not had any threads that it didn't like and have done many projects on my own but also take the monthly classes and a few extra like the cutwork needles; my favorite thing to use. You won't go wrong with the Viking. If I hadn't gotten such a great deal on my Diamond I would have went up to the Ruby Deluxe.
