I've taken up quilting since my Grandkids are all grown and my 4 year old Viking died. After repairing it three times in one year I felt my money would be better spent investing in a new machine. Enter a crazy pandemic and machine shopping became an online nightmare. I'd find a machine I liked but it was out of stock, go to another machine, out of stock, etc. Enter the Singer website (angels singing!) They displayed their machines that they had in stock as well as other brands to accommodate other tastes. I bought two!!!! So far I have only used the Quantum and it runs smooth and quiet. I'm also impressed by the weight of the machine, for the size of it, handling it is pretty easy. It won't be a chore taking it to a class. My two negatives are the instruction manual and the lack of information regarding what size bobbins the machine takes. I am happy to be a Singer owner again and I never thought that I would leave Viking behind after sewing on one for thirty five years.
