It's my opinion that sewing machines are alot like cars. You can get one one with all kinds of great features that you may never use or you can get something very simple and not as expensive to do a very basic job. As long as they are maintained with the proper care, they should last many years. I have 4 sewing machines at my house. I have a Kenmore that is very basic and have had it for 17 years. It does the jobs I need it to and still keeps on going. My husband has a Brother that does more than mine, and it works for his needs. (Yes, my husband likes to do crafts.) My daughters each have one that the very kind owner of the fabrac store gave them. They are older machines, I don't know the brand. She was going to throw them out and said my girls coulf have them to learn how to sew! Even though they are older machines, they still work great for learing and doing simple stiches.
The morale of the stoy is to find a machine that will do what you want and need, regardless of the name. If you treat the machine right, it will do what you need in return!
