I use a Viking 500 and a Vintage Singer 306W , love them both. The singer is cabinet mounted with a knee control and I can sew up a storm on any fabric with that machine. The 500 up until a few weeks ago was not the favored machine till I finally found a cabinet to recess the machine... now I use that machine a lot more than I used to. Love them both equally and have both set up and ready to go!
