It's the same one I ordered from there.
To make it economical, the parts need to be purchased for making 5 at once.
I'll take 2, does anyone want the other 3?
Cost will be less than $20, probably $15, I just need to source someone to do the threading on the polycarbonate tubing for us, and see what the individuals want for the open port side.
I've replaced my open port side on it with one of these...

Which allows a thermo to be inserted and removed at will without any loss of liquid, I treated a brass one, but I've contacted the manufacturer to see where we can source the Stainless one they make.
Let me know if you're interested,
