I did some research on sewing machines when I got my New Home Treadle. I Have a Kenmore Model 386. 18836. It has 36 stitches, Botton hole stitch on the machine also. Anyway I found out That a kenmore is made by Janome for Sears. This machine has never given me any trouble. Only when I do something with the settings and forget to put them back. I got it for Christmas 1999.
My sister has a Bernina,Spell Wrong maybe, She has given over $100.00 for a walking foot and a lot for other feet she has bought for it. It doesn't sew any better than my Kenmore. Whose walking foot was about $20.00 if I remember correctly. Soooooooo I guess it is just what floats your boat.
I do love my Kenmore, Will probably never get rid of it even if I decided to get a new one.
