Any number of remotes more than one too many remotes, and this $30 Logitech Harmony can consolidate them all into one device.
The Harmony 650 can control up to eight of your favorite home theater devices (from a database of nearly 250,000), and programmable macros like “watch a Blu-ray” can turn on all of the necessary devices, and switch a TV to the correct input with just a single button press.
