The majority of them (a little over 900) are the Acer X193WB. No frills 15pin DSUB models, no DVI. I agree that quality in most of the budget monitors can vary over different models. It truly is a numbers game. This model price varies from 90-125 bucks depending on the retailer. So even if it last 4 years, the price per year is pretty low. As for the failure rate in 4 years, we will have to wait and see, but I agree that they many will start dying.
