2nd computer monitor recommendation?

What's the calibration like if I may ask? I think my mate has a MacBook Pro and a Dell (not sure of model) and he had a hard time calibrating the screens.

Cheers

I'm not using it for any photo editing (other than just personal stuff) but it seems ok. Mine is perhaps a little cold but there is quite a lot of range to adjust.
Obviously it's not going to stack up against the professional quality monitors at three or four times the price though.
