Just like you I went from the 12x to DX-18 I held out until Best in the West last year and at that event I couldn't turn around without seeing a DX-18 in someone's hand. I talked to all the guys in the know and heard great things so I bought 2 DX-18 G2's. Like you I am diligent in RX setup, dual batteries and checking data. One of my 18's didn't have great data so I sent it back and they replaced the board problem solved. I range checked both radios after the service bullitan and I had solid connection over a mile no problem. I don't know of any incidents second hand either. I have been very happy with them.
