I do like both but the 7300 is in a class and price range all by itself right now. Since he already decided on the 7300 I won't go over the differences I find using one vs the other.
Let's just say the 7300 would have been a good choice But, you're going to like the 1200. Make sure the radio they ship you has the latest firmware update. Yaesu didn't make it easy for users to update the firmware. Also remember that add-ons for the 1200 like the FFT-1 board and SCU-17 interface are expensive and make the 1200 more expensive than the 7300.
What exactly does the FFT-1 add besides a decoder?
