Concerning thermal transfer compounds, I saw a computer forum where a guy tested various kinds, from high dollar to toothpaste! The toothpaste performed nearly as well as the most expensive for quite a while-it dried out and lost much of its conductivity, but was still better than none at all.
The Blue Ridge Company is the best place I found to order PEX. They have 1/2"
American made RHT oxygen barrier PEX-C(which I used even though I have an open system), which is currently 30 cents per foot with free shipping, and lengths from 300ft to 1000ft per roll. I tried 4 brands of PEX including A,B & C crosslinking methods and theirs was noticeably easier pulling, more flexible and more kink resistant than the others. PEX A is supposed to be more flexible, but the brand I tried wasn't as good as the RHT, plus the outside was "grippy", making pulling/handling more difficult.
