I had one heavy Kenmore for more than 30 years, but when something went wrong with the tension and I had to take it to a repair shop half-way through a project I realised that one machine is not enough. Not only is the Kenmore too heavy to cart to classes, but having a backup machine is wonderful. I bought a $65 newer Kenmore at an estate sale; all of my accessories fit the new machine and it's great to take to classes. Then a friend bought a hugely expensive embroidery machine and I was envious, so I bought a combo sewing/embroidery machine from Craigslist for less than $200. Now I wish I had an actual sewing room so that I could have them all out at once.
