You will always be sorry if you don't! So go get it!

My Mom had a Singer 401 for a few years when I was growing up, too bad she traded it in for Singer golden Touch & Sew 758, nasty cranky machine. I much preferred the 401; it sewed better and with less hassle.

I LOVE my 401A! It is 55 years old and going strong; been in hospital only once. I keep her oiled and lubricated and she purrs. The many stitches and cams make it as versatile as any Bernina or other fancy machine. You just have to learn how to use her. Be sure to get a manual to help you.

By all means keep the 401A! I have one, and it is an absolute work horse! I like it better than any I have ever used.

you can get a free manual here:

you will have to put 401 where it says search then select search
then all you have to do it print it out

Thanks - i downloaded the manual so I can print it out later (in a few days) I am so excited. I already named her - ha ha!
I kept opening her up today and just looking at her! isn't that crazy. the desk/table has a drawer that has a bobbin holder attached to the side - i love it! she needs some work but that is ok!

Wow, that's great. I am so glad that you didn't pass that one by. It's nice to keep in in the family, too.

I have a Slant-=O-matic 403 Special and love it.

I like the Singer 403, too - it is my go to machine - I've set up others but that is the one I use

I recently purchased an inexpensive 403a on eBay. New to this game I found why other bidders passed it by. Evidently it had been dropped and tension assembly shaft was bent beyond repair. I replaced the assembly with an after market $11.95 assembly. Now the problem. It ranks with my 15-91 and 201-2 so I have three go-to machines. I assume the 401 has same qualities and more than the 403.
