There are several brands of Korean monitors that use the A grade IPS panels that give 2560x1440 resolution, and cost with shipping is about $330 on eBay.
These are said to be the same display panels used in apples cinema displays, but apple rejects some because of dead pixels, backlight bleeding, etc. that's what makes these panels grade A instead of A+.
From the research I've done most people receive them with no noticeable issues. If there are dead pixels it's usually only 1 or 2, and on a display this size with this resolution you will most likely not notice the pixel unless looking for it.

Also note that there is one seller on eBay that guarentees less than 4 dead pixels, and others are less than 6. Make sure to read the terms of each seller because their definition of a perfect monitor vary by seller.
