Replace Concertone, keep A,B,C zones

[tlhintoq]

My 2006 Sandpiper toy hauler came with a Concertone sound system. It's no Jensen or JVC, but not aweful.

What it does have going for it is the control of Zones A,B,C so the music can be piped to the living room, bedroom or outdoors.

I need to replace it because it fried in the last storm. I could replace it with another Concertone on their repair/replace/upgrade program for $249

But before I do that I was wondering if anyone had any other recommendations. I really only care about 5.1 in the living room and the ability to route the music to the bedroom or outdoors. I don't need the built in TV tuner for sound as my living room is run by a PC with tuner anyway.
