Steve,
Well I did take a deep breath before ordering. While I have never had
a lot of MFJ stuff, the stuff I've had over the years has all worked
fine. I know others haven't been so lucky, but I've had this one over
2 years with no problems.
I can't compare to the LDG since I've never owned one. At the time of
purchase I did compare the specs for both. The LDG had 6 meter
coverage, but I work very little 6M and no amp, so no big deal. The
MFJ offered higher power (1.5K vs. 1K) as well as the ability to
automatically lower rf drive and change to cw for tuning, while the LDG
required you to do all that manually. The MFJ also had the amp relay
connections. Of course LDG may have something out today with more
features.
Truth is, I've switched the MFJ and the Palstar manual tuner in and out
of the system a number of times over the past 2 years. Each has it's
benefits. I would have loved a Palstar auto tuner, but too rich for
me. The Palstar auto had a motor driven roller inductor and either 1
or 2 moter driven caps. It just went out of production, but a new one
is coming soon, although I've not seen any specs on it.
