Input on enamel pin manufacturers?

Hello!

I'm currently looking into making my first enamel pins I had a few factories reach out to me and I asked for price quotes from them, as well as Vograce which I already have experience with for other product types. I would like to know if anyone has experience with any of these manufacturers, or perhaps can recommend any other ones.

The options for now are Vograce, Amazpins, Worldwidepins and Pinworld.

I likely will not go for Worldwidepins, since they are by far the most expensive option out of these, but I am still willing to hear any comments. With the info I have right now I'm most torn between Vograce and Pinworld, but I would like to hear any personal experiences with these manus to help make my final decision

Thanks in advance!
