Have an old Kenmore that I sewed on when my children were small (now in their 40's) and it still works. Have a not so good 1 1/2 yr old Singer but it works. Have a small Janome for classes and like the way it sews. Recently bought a Singer Spartan (made in the 1950's) and is a workhorse. Have used Babylock and have an Elna Serger. However, saving the best to last, I have a Husqvarna Viking Designer 1 and nothing I have used holds a candle to it. Recently, hemmed a pair of jeans and it went through the folded cuff and seams like they were butter. I have never had a machine that I didn't have to pull from behind and push the fabric in the front and lift the presser foot over the seams in jeans. The Viking sews through silk organza as easily. I hope the D1 outlives me...LOL
