Wow, I've actually been preaching this for years.
You see the 3007WFP-HC is actually not inferior to the U3011 in almost any way.
I've debated with a number of people, and none of them could name anything past the panel revision - which if you know the quality of the 3007WFP-HC, you would know to ignore.
Basically, you get an absolute staple of the monitor industry for half the price it used to go for.. I really could not
recommend it enough!
I got mine.. almost 3 years ago, directly from Dell as a Manufacturer Refurbished model - it was identical to my friend's brand-new one from 2008.
Dell don't sell it anymore, but I've purchased Dell monitors on eBay from reputable sellers and have always been pleased.
This is basically the best choice for a monitor in my eyes.. if you can afford it
