And then there is the Austin QRP groups "VIA" VNA that can be a 2-port or
simple 1-port analyzer (builder's choice) that will set you back less about
$200 with options.

I've found mine very handy and have used it out at the tower.

without getting into what's good/bad because I've not looked at it in
any detail, there's a whole crop of newer small VNAs these days
http://pocketvna.com/ - about $400
https://www.sdr-kits.net/index.php?route=product/product&product_id=70
- VNWA 3EC (DG8SAQ) - about $600
https://www.arraysolutions.com/vna-2180 - $1000
There's also mention of a miniVNA, but it doesn't seem to be available
any more.
The TAPR/TenTec and N2PK appear to be no longer readily available as
assembled units - they're both >10 years old, and probably need parts
that no longer are available
