I have a pair of the easel style 23" Apple screens. I love the increasingly rare 1920x1200 resolution, and the screen quality is great. But I don't need both, so I am selling at least one (potentially both, to get one 27" 2560x1440 monitor), but don't know how much they are worth. I have 2 ADC to DVI converters, one for each monitor, which appear to be worth quite a bit on their own. One has some damage to the rear leg (a piece has broken off along the line of the attachment bolts, but I have the piece and it will be glued back on), but it still stands securely even without a repair. I intend to remove the outer casing to remove some dust and particles that have got in between the shell and the body, but other than that and the leg mentioned above, they are in good condition. They work well with my 15" rMBP via a Mini DisplayPort to DVI adaptor, and the laptop can fit between the front legs of the monitor if using in clamshell mode or storing. Therefore I think they are not outdated. How much do you think they are realistically worth? Does the leg damage affect the value much?
