        I have the first 3 of these and they all have their
strengths and weaknesses.  It really depends what you are
trying to do as to which is best.  

AEA CIA-HF:  The swept display on this makes it excellent for
measurements where you need "the big picture".  For example,
when tuning a Beverage, you adjust the termination resistor
for the flattest SWR over the range of interest.

Autek Analyst:  Best for simple measurements where you need 
portability, such as tuning a gamma match at the top of your
tower, but it reads only simple measurements (e.g. SWR) and
not complex impedance.  

MFJ 259B:  Best overall analyzer IMHO.  Easy to get very accurate
measurements since it reads complex impedance (but without the
sign of the reactive part).  This makes it best for tuning 
phasing lines to exact multiples or checking antenna resonances 
very precisely.  Some have problems with BCI overload but I live
far from any broadcast stations and have never had any problems.

        The last two are very easy to accidentally turn on and 
drain your battery.  If I only could have one of these, I would 
definitely choose the MFJ-259B.
