Trouble is, that source does not give a very good idea of what many will pay for that monitor. Those 2 sells
want 135 bucks for the monitor, doesn't mean they'll get it. And they likely won't. Who is going to pay 135 for a used Acer when they can get
THIS for pretty much the same price? Or
THIS one for a few bucks more with a nice MIR and free shipping? Hell, I only paid around $180 for my 25" monitor new a couple months ago.

These are real world used prices, IMO. Those are pretty old parts.
