I too was bitten by the vintage sewing machine bug. I have a featherweight for each of my grand daughters when the time comes, I have a regular treadle and a chain stitch treadle, my dmil's singer 401a (needs work), and a couple of auction bargains sitting in my unfinished room upstairs. But I fell in love with the latest bells and whistles for quilting, auto tie off, needle up and down, etc, etc, of my pfaff QE 4.0. I used a featherweight for classes, and guild sews days. The old machine stitches are more beautiful IMO, and I feel so different when using one of the old machines, kind of like in touch with the fabric and the process, but I am a modern woman. Love creature comforts!

Nothing wrong with wanting something new with all the bells and whistles, but I would keep my old dependable too! Ask me how I know????

I have both vintage and new. Both have their places, and you will find now matter how many machines you have you will have a favorate go to machine. If you love your vintage stay with it.

If you can afford it i say get what you want.. If you feel comfortable with selling the other one go ahead... Life is short.. do what makes you happy as long as you are w/in your means..

Thank you all for your sharing your toughts. I feel better knowing I'm not the only one who likes bell and whistles. On the other hand, I sold a brand new Viking Tribute a few years ago (excellent machine, never gave me any trouble) because after finding a vintage Bernina 831, I was just not enjoying the Viking anymore. Mighty, I think you are right: every sewing machine have his place.
It would be so nice to have a dealer who would have "in stock" all brands of sewing machine (vintage AND modern) to be able to try it all and decide after. One have to go by trial/error.

Perhaps if you find it a nice home you will feel better about getting a new machine.
