Newegg offers the refurbished Logitech Harmony 350 8-Device Universal Remote, model no. 915-000230, for $14.99 with free shipping. That's $10 under the lowest total price we could find for a refurb elsewhere and the lowest total price we've ever seen. It features support for up to 8 devices, Watch TV button, and programmable favorites.
A 90-day warranty applies, although it's unclear who backs it.
