I knew I wanted a seam guide attachment for my Featherweight, since its original needle plate has no guidemarks. (Yes, I know I can buy another "original" with the marks and I will — just haven't yet.) The FW came with many attachments. Unfortunately, the seam guide wasn't one of them. So I bided my time on Ebay and bought a reasonably priced lot of sewing machine parts which not only included the Singer seam guide but a Greist version too. (And some other weird stuff I have no idea about. One day I'll post pics of those things too.)
This is the Singer seam guide on the Featherweight:

And here is the new resting spot for the Greist seam guide, on my coverstitch machine.

The stack of Post-Its works fine, until it gets accidentally knocked loose. And it does have to be "renewed" every so often by peeling off the old back sheet which has picked up lint and threads, etc. and lost its sticky. Eventually, I could go through tons of these things, which makes the Greist seam guide "greener" both in terms of not wasting sheets of Post-Its and it being rescued from a landfill. Nice side benefits for a nifty old gadget, eh?
Here's a blurry photo of them side-by-side. The main difference is that the Greist version has an ugly brown plastic capped screw which rides permanently in the groove. At some point, I may ask my husband to snip it off so I can sub a prettier silver screw. For now, I'm dealing with it. Brown may be one of my favorite colors — but for clothing, not on sewing machine attachments.

So now you're wondering where to get one, right? Well, the first place to look is Ebay. Search on "seam guide" or "sewing machine attachments" or "sewing machine parts" or even "Singer attachments." Of course, once you have the Singer name involved, especially the "Featherweight" label, the price may go up. These things are plentiful though and come branded by Singer, Greist, Elna, Kenmore and more. So be patient and you should be able to pick one up for under $10. You might even get it with a bunch of other interesting stuff like I did.
I tried to find a current version, but I wasn't having much luck with anything at a reasonable price. I did find this, which looks interesting. I have no idea about the website it's on though.
