Acer offers its "scratch and dent" Acer 23" G6 Series G236HL Bbd 1080p LED-Backlit LCD Monitor, model no. UM.VG6AA.B01.HU, for $59.99 with free shipping. That's $31 below last month's mention of a new unit and the lowest total price we've seen. (It's also $54 under the best deal for a new unit today.) Features include a 1920x1080 (1080p) native resolution, 5ms response time, and DVI and VGA inputs. A 90-day Acer warranty is included.
Note that this item may have some cosmetic damage, like scratches on the side panels or top covers, and possible dead pixels.
