I use an iiyama 17" and its cracking, i've also used the 18.1" version and that is even better. The 18.1 also has a super slim bezel which gives it a very sleak look. Both with DVI input and extras like USB hub. The DVI is a must, the USB hub is fairly useful, saves me reaching behind the computer to plug the empeg in.

I think go for a company that has a good reputation because you're going to spend a lot of time in-front of it i imagine. Also no dropped pixels, however i don't know how common these are anymore. Wasn't the cheapest but this is one item where i feel the extra money has been worth it.
