in your price range, this is what I would use...
MikroTik
ETA: These units are for the more knowledgeable users. They come with a default configuration that would work for most home or small office networks, but the wireless is disabled and would need to be enabled and set up. These units are serious routers with more features than most people could ever use...
Edit #2: The Ubiquiti units are great, but the UNIFI Access points are not routers. You would still need a router. There is a UNIFI router, the UNIFI Security Gateway, but it has no wireless built in and you would have to buy the access points extra. It's over $100 alone, plus the cost of the access points. They run about $65-70 each. This might make sense if you have a large house that needs more than one access point to cover it.
