I agree.  I have a Palstar 1500 balanced line tuner and it is  the finest I have ever owned.  I use it with a 2.2 MHz full wave loop (not a typo but that's another story)fed with 450 ohm open line. You do need a "cheat sheet", however.  With the two capacitor and one inductor knobs was well as High/Low C and L swiches, it's almost impossible to rapidly tune up on a new band without it.
