Patrick, a VNA is useless without a good pair of cables, and a cal kit.
A mechanical cal kit is going to set you back $6K
And a good pair of cables will set you back maybe $500
I don't want to get into adapters, one adapter can set you back anywhere from $200 to $500 from SGMC.
What frequency is precisely the question though.
I was looking at the 6 GHz models, which seem to be fairly affordable, compared to the $300K PNA-X's we play with at work.
This is not a cheap direction you're looking to go into.
I have heard there is a lot of surplus up there in silicon valley, I usually go to the TRW swapmeet at work and have seen a couple network analyzers there, the last one I saw only had 3 port measurement, and I didn't have $3K. I have seen an 8510 though, and that thing is a real workhorse, dated, but that and a good sweep generator to 20 GHz and you'd be set for life.
I wanted to get into this too, but I got no money. I was thinking of building an adapter for the scope instead, after all, all you need are the power sensors from AD AD8307's, a triggered sweep source, some directional couplers, and you can build your own. The hard part is finding the time.
