If you bought the 2407 now it would a be a waste because Dell's prices fluctuate up and down depending on their promotions and the current price RM 2300 is on the high side. For reference, I bought mine at RM 2000. The 2707 though is currently at the lowest price I've ever seen it. If you want to base your decision on which model is more "worth it" then it would definitely be the 2707.

Despite what the review says the 2707 does not necessarily produce better color over the current model of 2407. The latest model of 2407 (with the HC suffix) uses a different backlight that can supposedly achieve a 92% colour gamut, same as the 2707.
