Logitech offers the factory-refurbished Logitech Harmony 600 Advanced Universal Remote Control, model no. 915-000112, for $49.99. Coupon code "MLC126HN" drops it to $36.95. With free shipping, that's $9 under the lowest total price we could find for a new one. This universal remote can be programmed via your PC or Mac to operate any TV and most other A/V devices. (It's limited to five devices.)

A 90-day warranty applies, although it's unclear who supports it.
