How many APs are you deploying? You can deploy a Cisco controller and two 2702i APs for less than $2k using a Mobility Express bundle. And the 1702i would be cheaper and still fine for residential. The controller is licensed for up to 25 APs. The Cisco product may be more difficult to configure than the other options. Also note that unless you purchase a support contract you will not have access to software updates. But the product has been solid in my experience.
