Hell, if I didn't buy something just because it had been discontinued, I wouldn't have half my equipment.
The IC-RX7 is still pretty widely available, but discontinued?--that might explain why it has been heavily discounted lately. I like the RX7's menu-driven display better, but I heard the R6 has a better speaker.
Not that I need another receiver....transceiver, maybe.
I think I would go with the R6, I think the 7 has been discontinued. I bought ARC6 and the PC cable to speed up the programing.
