refurbished
I had a very good experience buying a refurbished 15" studio display from the Apple Store online. No stuck or dead pixels, and a much better display overall than my sony 17 sfII.
The display's back plastic shell has a couple of seam lines, but they are visible only upon close examination. The TFT panel looks to be perfect.
You can get a refurbished one at the Apple Store for $2199, I think. I don't know, when you're talking about $2k, you might want to spring for the new model. Then again, if there's a problem with the studio display when you get it, you can always take it to a apple specialist and have them examine it, and replace any parts that are defective, under warranty.
Also consider going for the 17" studio display, which gives you almost as much screen resolution as the cinema display. They have them refurbished at the Apple Store for $899. I suspect that the cinema display will see a price cut or be discontinued or otherwise refreshed next year, simply because it has been around for so long. I'd speculate that whatever products they change or update, Apple will still have a massive display in their product line for the foreseeable future.
Good luck,
Colin
