Well, first a FT-1000MP and now IC-746 or IC-738. All used, out of production old radios. It seems you’re intent on saving a few bucks and buying used. In that case, I’d advise buying local, from someone you know and trust, and get to test it out before you buy. Otherwise, you don’t know how they were used (or abused), and if the sellers aren’t telling you about some hidden defect/problem. They’re all old enough to have been operated for a long time.
I know many on here promote the savings by buying used, and they’ve been successful doing that. Especially if they’re current production radios. But buying old, discontinued stuff is another story, and you should be extra cautious.
Again, my advice is to consider buying one of the current Icom or Yaesu radios in that $1,000-$1,500 price range, either new or a recently used one if you want to save a few extra dollars. Good luck!
