No doubt that Dell 2410 is a good monitor but I would still go with Asus PA246Q(Pro Art series) which is exactly a similar monitor with same panel and electronic components(more or less) and is cheap in comparison.
I personally like both of them...but for me Dell is loosing it's value.This was the last good quality monitor apart from similar 30 and 27 inch monitors that Dell released.(Also a bit old)
Asus's Pro Art series is amazing and you can also check some monitors from Samsung (pro series). Lacie also have some good 24inch monitors for professionals.
I am not quoting "EIZO" here because for that you have to buy a Ferrari "ENZO" too..
It all depends on what you want to do with it..
