Since these come with s-params I grabbed one of them. Shipping is very high, but ultimately still worth it for me to have items which I can use as a calibrated reference.

The question is, did you pay soon enough to get one of the sets. I know I paid for one 14 hours ago.

Yeah I have one of them locked in. I was in a meeting at the time and was surreptitiously putting a payment through on Paypal while nodding my head and looking interested in what was being said. No idea what I have promised to deliver on, but hey at least I'll have a cal kit.
Then I screwed up the email address and had to cancel the payment and put it through again. It was about 23 hours ago.

Congratulation for your score. When i made the purchase, i wish i can have yellow case instead of black. But i choosed cheaper option of 'whatever color mostly in stock'. In the end i got... yellow case ;D

I'm not convinced you can treat the Kirkby kit as some form of calibrated reference if you want to start playing with Cx and Lx factors. I'm not an expert on SMA-SMA connector variability but you can't avoid having a subtle discontinuity between your SMA test cable and the Kirkby SMA cal connector because you can't expect two solid dielectric connections to mate perfectly without a tiny (uncontrolled) air gap and without some form of pin mating variability as well. So I don't know how much this will affect the phase response across a 6GHz bandwidth. A 3.5mm to SMA connection should be a lot better in this respect.
