WTB - light brakeset/stem

Building a WW road bike and looking for a lightish brakeset.

Don’t want to spend more than $100, but I figure there’s got to be a few cnc sets floating around out there.

Also if anyone has a light stem they want to get rid of, I’m looking for something under 130g.

Thanks.

I’ve got a few stems in the stable. What size?
Brakeset: Zero Gravity Negative G. Not in your price range, but $175 shipped.
