I had the Ruby and traded it in for the Diamond Deluxe, there wasn't anything wrong with the Ruby, it was great. The Diamond just did more and had a bigger hoop. The Royale at the shop I go to has a great rep and has bigger hoops and more features than the first one that I had. I'd buy another one in a second. Both machines aren't picky about thread, self adjusting tensions, I've never had to change my tension sewing or emb and they are very easy to learn.
