Summary: If you only need to control three devices, the Logitech Harmony 200 is the best universal remote you can buy for under $20.
Pros: The $20 Logitech Harmony 200 is a well-designed universal remote with great ergonomics. You program it via streamlined wizard-style setup software (Mac or PC) that's optimized for tech novices
Cons: The Harmony 200 only controls three devices and requires a computer with Internet access to configure. For just $40 more, a step-up model adds an LCD screen and uses the activity-based commands that Harmony is known for.
