Ruth,
I mostly use old Singer sewing machines - piecing on a Singer 301 or Singer 221. I also love using my 1967 Kenmore. The stitch quality is unbelieveable on these oldies and I love the fact that they sit right where you place them. A while back had the opportunity to try and help fellow sewer by trouble shooting a machine for her - seems like I spent most of the time chasing the machine all over the table.... I do have a computerized New Home machine have had it to the sewing machine hospital several times because after sewing for about 15 minutes it starts to squeal and the tension goes all funny. Give me the old metal Singers and Kenmores any day. They are wonderful - a bit of oil and a little grease here and there and they run forever.
