[RFI] RF Impedance measurement

I have several of these devices and I prefer the MFJ-259B, as it is easier for me to operate.  However, we all have different needs; the AEA/Timewave CIA and VIA, and their predecessors, are pretty slick pieces of gear too, but again, not so easy to (in my opinion) operate, at least as stand-alone equipment. I carry an Autek RF-1 with my portable setup -- but  I find that hard to tune precisely enough.

I could use your thoughts and experience with measuring RF impedances with 
"less than lab quality" commercial equipment.  I would like to measure and 
characterize things like antennas, baluns, ununs, etc over our typical HF 
range.  I have an old MFJ 259 but it lacks direct R and X measurement.  So
