After bumping into my desk yesterday, I managed to damage my current monitor (BenQ RL2455HM) and am now looking for new monitors (finally got the money to go for a dual screen setup). The monitors I'm thinking of buying is the BenQ GL2460HM (http://www.amazon.com/BenQ-GL2460HM-.../dp/B00IKDFL4O).

Now I'm wondering, is this monitor any good or are there better monitors around the same price range (about 180 euro for the shop that sells it in my country)?
Furthermore, there is also a 27" model available (http://www.amazon.com/BenQ-GL2760H-2...eywords=GL2760). Is there a big difference between 24" and 27" monitors (and if so, is it worth the extra money)?
I've never had experience with 27" inch monitors, but a friend says he's never going backto 24" after having bought a 27", so this peaked my interest.
