Home made one work as good as any commercial ..even the aluminium one work great.
You are overthinking this. A gas check is a simple thing. You should worry more about your cast bullet consistency in weight and fit to bore than anything else.

I ordered mine from Sages Outdoors.

I have an order from them inbound too. Customs apparently needed a couple weeks to look at it but it's on the way again.
Hoping to make my own dies like Yomomma one day too.
