I don't know anything about the Viking machine, but I've had my Brother 1500 for about 5 months now. I LOVE it! I love the big harp space and that it sews right through thick stuff without any problems. I was a little concerned when I ordered it that I would have a hard time controlling the speed since it doesn't have a speed selector, but it has not been an issue at all. I can sew one stitch at a time with ease if I need. I rarely sew at top speed though as it's WAY too fast for me!
