I'm planning to do work myself, just want to add some functionality on my 67' 150 w/o paying the new Garmin prices. I was considering just a standard used 760 channel comm but am entertaining the IFR cer't 300xl.
When about are you going with the upgrade? I want to get rid of that kx-170 and add something more functional w/o going new Garmin route on this 1967 150.
