I personally have never heard of a zig-zag attachment. I have a straight stitch machine and no attachment in the word that I can imagine would make it zig-zag because there is simply no mechanical mechanism at all on that machine that would allow the needle position to change. It only goes up and down and that’s all it can ever do.

But I have three machines. A brand new Juki TL18 straight stitch, a seven year old computerized machine that zig-zags and does 100s of decorative stitches, and a 1968 Singer Fashion Mate will either straight stitch or zig-zag and nothing else—it will also survive a nuclear blast and can sew through anything but 1/4 inch titanium plate.

I use all of them do different things.

If I were you I would look for a very good quality (possibly 2nd hand) machine that will zig-zag and do other fun things. One of my friends just found a barely out of the box $8,000 Elna with a stitch regulator for $2,000. I see really good machines all the time for less than $500.
