U2410 is a 2009? monitor IIRC
What I find is 2009 monitors and before are almost always fine. The problem of course is finding a monitor that old that hasn't been abused for the last ten years.
The only thing I'd say definitely avoid is the monitors that only use two CCFL bulbs. The bulbs are generally brighter to make up for the missing two and die earlier. I also find they tend to be more likely to cause eye strain (and have aggressive PWM)
U2410 owners would you drop 200 on a new one?
