Here's a few more things to consider:
l bought about 35 years ago an Elna. It still sews beautifully. But, as the other ladies , stated it has more bells and whistles then l use. Plus it is very heavy.
l bought about 5 years ago, a White. It's a basic machine with a built in buttonholer, and a few stitches. l use it constantly and have had no problems. It is much lighter .
l do recommend, that you stay away from the electronic sewing machines. The quilting classes l've gone to, the ladies who have them seem to have a lot of problems adjusting them. We had a fella from the local Singer sewing centre come to our Guild meeting for a talk. He said , that those electronic machines are not made to last very long. Also, make sure you have them on a surge protector bar. If you have a power failure and the power comes back on rapidly it could destroy some of your electronic components. And your warranty will not cover replacement of those parts. Also,parts on those machines are hard to find he said after 5 years.
