Amazon has a ton of choices. Beware the real cheapies...sometimes they don’t spin. Ask me how I know.

I used a bundle of them to put on giveaway bikes to my students a few years ago.

A few of them are actually really decent at the $20-25 mark if I recall.

And Soma or VO have SR Silstar or a similar MKS model in the classic quill. Personally I like the track like versions.
