A 43' vertical is a serious mismatch on 160 and 80, its too short, has a 
low radiation resistance and lots of reactance. That makes a tuner run a 
high loaded Q and have lots of circulating current in its circuits.

I don't know what is in the $250 box, likely a loading coil with some 
sort of switching like a series resonant circuit for each band to select 
the right amount of loading coil. There wasn't a manual available for it 
on line to learn more.
