Hi, there are quite many choices between tiny hand-held units like Autek
Research VA-1 vector analyzer and computer/laptop connected VNAs like
N2PK VNA which gives more accurate measurements. This last one is
basically a kit, but not too complicated to build at home and is quite
multi-use device.
Both have been useful and done their jobs well.

This request from last year did not garner many specifics other than that
one should be aware of disturbances from other stations when using most
available instruments. One mention of the AIM 4170 was made by K6MHE and
the use of a GR bridge was mentioned by several including Walt.

If might be interesting to several to learn what K1PO ended up using.

While I have a GR bridge and the CIA hand held meter, I have found the AIM
4170 to be ideal. It ends up being used for several tasks and has not been
disturbed by RF from others when connected to an antenna. Its ability to
characterize a crystal is great - especially to someone who has done it the
old way. This evening, I confirmed that one can use it to characterize a
piece of coax for velocity, Zo, and (matched) loss. . . . and it is very
easy to store the Z vs. frequency for latter comparison. . .

Another data point. 73, Mac N8TT
