Steve,

Yeah, the QC at MFJ is always a question.   It's one reason I went with a 
THP amp instead of Ameritron.  I would also like 6 meters and even though 
the  LDG's power is limited  to something like 250 watts on 6, it is still 
nice to have that band in the tuner.

Good luck with any future purchase.

73, Steve KW3A
