to PC's, and that market is covered anyway. I thought a 259 revision wth
direct conversion receivers and a wide frequency range, and a calibrate
function, and just basically do what the 259B does now, would have been much

The RigExpert handheld series of complex impedance analyzers pretty much fit 
that goal.  The AA-54 is in the same price class as the MFJ-259B and has +13 
dBm output power.  It doesn’t have the frequency range of the 259B but it 
will accurately cover HF through 6m.   At roughly 2x the price, the AA-600 
gets you a serious 600 MHz handheld analyzer with OSL calibration and PC 
graphing connectivity.
