I would keep your machine (you will be sorry if you don't, speaking from experience) also, 125-160 isn't a lot of money today! that machine will outlast many, So go for it and enjoy it!
My hubby and I have a deal, I stay out of his garage and he stays out of my sewing room :roll:
I have a 1951 singer in cabinet
a Janome 9500
a Janome Platinum
a Singer serger almost on it last leg, (dh said he would buy me a new one for Christmas if I want) not sure if I am ready to give up on this one
Future plans: a 301 Singer and a little featherweight just because they are adorableand a real work horse. And last but not least, another treadle, oh gosh I sold mine when we moved and so sorry!
