I've had my Viking 6020 for 44 years and it is the only machine I use. When my kids were small I sewed all their clothes including jeans and snowmobile suits as well as their underwear. I also sewed and did alterations for other people. My husband worked nights and I sewed nearly every day from 8pm until midnight when he got done. It still works like new even though all I use it for now is quilting. Now granted, it is not an electronic machine like the new ones but it is a workhorse! What I like best is that I can give it a really thorough cleaning myself and don't need to take it in for regular service. The only trouble I've had is when I lost my regular foot and the ankle in the waste basket when I had the walking foot on. Must have slid off the table and into the waste basket unnoticed. I had no trouble replacing it and am still really happy with my machine.
