TigerDirect via eBay offers the refurbished Samsung 23" 1080p LED-Backlit Monitor, model no. RB-RFBS23B550V, for $134.99 with free shipping. That's the lowest total price we could find for a refurb by $28. (It's also $151 under the best price we could find for a new unit.) Features include a 1920x1080 native resolution, LED backlight, HDMI and VGA inputs, and more.

A 30-day warranty applies, although it's unclear who backs it.
