Yeah, i am able to get some really good deals on those monitors and they are much cheaper than actual sonys. I am wondering if i should upgrade my monitor. I have a 753DF and can see it flickering at all resolution rates, and am not happy with it at all. I even went to the doctor about it to make sure it wasnt a brain tumor or something and he said i just have unbelevably senative eyes. Would you recomend upgrading to the 19 or 21 inch monitor. I work around my monitor at like 2 or 3 feet away. Would 21 inch be too big? and would it be worth the extra $250 to go with the 21inch?
