Oh dear.. I checked XS last night.. Haven't been there in forever, noticed I had a 5 month old PM offering a 2 stage phase that could hold -90C @ 300W load for $2k, and a SS 300W load @ -30C for $400.. I wish I had an extra bit of $$$, and that I'd checked a while ago. Now I'm getting into checking there too.. lol. I'm gonna be running into the issue of too many forums to check.
