Cisco has really made configuring a WLAN controller and the associated access points simple.  Today I configured a Cisco 2504 WLAN controller and 6 1242AG's with 2 SSID's in less than 2 hours.  That is including the time it took to un-pack everything.  I love it when a product works and makes my job easier.
