I bought mine used on e-bay and spent too much for it.  Failed the 
third day and cost me $70+shipping to get it fixed by MFJ.  I ended 
up spending more than a brand new unit ;-)  But is compares well with 
Bird43 measurements (which are 95% accurate) so good enough for ham 
use at my place.  I modified mine to operate on LF for tuning loading 
coils on those "short" LF antennas.  See my website under tech topics.

I ran it on a 4AH gel-cell for a couple years until I got tired of 
lugging around the battery (installed ten NiMH AA cells and charge it 
with the bench PS).  It is very handy for those quick checks of 
antennas or cables.
