You'll love the Ruby, go to Vikings web site and compare the Topaz and the Ruby, it has great features. I can't think of any cons, its easy to use and learn. I never had to adjust my tension because it did that, it also has design postioning, it loves all thread. Congratulations. I hope you get a good offer. The Topaz is still a great machine so you should get a great price on it for a trade in.
