Any suggestions for a decent co2 check valve? Last time around I had one of the stainless steel ones that I heard were decent but it froze open within a few months.

Mcmaster carr sells them. Works better then any others I have found so far.

For what it’s worth.. i used these cheaper plastic ones on Amazon and worked great for 2 years. The did get some drops of water inside the lines, but nothing happened,, they just stayed there rather than running back more. and the valve kept working.
I think you’d be good with any check valve. They are simple enough that it would take some real effort tk
Make a bad one.

Used these for my diy co2 set ups and they were super cheap and effective.

I think they all leak a bit if you turn your CO2 off at night and second stage is high enough. I just use the cheap ones also and use the JBJ as a trap instead of a bubble counter to protect by carbondoser.
