It all depends on the degree of precision that you need for whatever 
project you happen to be working on. I work all bands between 1.8 MHz 
and 900 MHz, and I occasionally need test equipment for all of them.

Also, errors can add with either a positive or negative sign, as a phase 
angle. Impedance measurements with a vector analyzer are done with a 
mathematical equation that can be the difference of numbers that are 
nearly equal, so a small error in the raw data can cause a greater error 
in the measured Z.
