Thank-you for your replies. Sorry about not being complete in how I sew. I'm a quilter, very rarely sew clothes and if I do I have plenty of modern machines with fancy stitches. I'm really attracted to the funky looks of some of these old machines and love the colored ones!!
I'm going to look into the 403, sounds like I don't really need a 301 since I have a featherweight. Of course I don't actually NEED any more sewing machines. But the mechanical ones are nice because you can do a lot of the maintenance yourself.
I was horrified the last time I brought my Bernina 150 in for a repair. And he says if the same thing happens again I will need a $200 part, then pay labor. I don't even dare use it anymore, I'm so afraid it will break on me.
Anyway thanks for all your info. I'm really learning a lot here.
