You can see the various options of equipment that may suit your needs. It should be inside your budget for the most part.

Adding (separate) wireless speakers instead of a whole unit (like the Sonos system does) would be a different animal- closer to a real AV receiver. Long term though, you might want to throw up/install simple pairs of speakers in your deck areas if you don't end up with a portable unit like the Sonos (etc.)
