Agree 100% with Clint. IMHO, the FT-65 is in no way a "successor" for the FT-60.
Now, an honest question: If the FT-60E has been discontinued, and even though Yaesu USA has stated several times recently that the FT-60R is still in the market and it is not being discontinued... Does someone recall Yaesu (or any other big manufacturer, for that matter) sharing in advance their plans about discontinuing any particular product? Sellers, sometimes, use that as a selling strategy. Manufacturers... rarely; they just do it (as Yaesu, apparently, has done with the FT-60E in Europe).
I was waiting for a huge discount sale of FT-60s when the FT-70DR appeared, but that didn't happen. On the other hand, it is the new FT-70DR the one that has been on sale for several months now.?
Honestly, I would go with the FT-70DR if there was a 6xAA battery holder available for it, but there isn't, AFAIK.
