I have the opportunity to buy a very nice one for ~$250. I know there are a lot of nice monitors for that price - it's worth noting I largely just want it for docking purposes for my MBP every once in a while.
chances are it has taken on a brownish tint and lost a fair amount of strength on the back light. it's a gamble at best.
These were LED panels. I don't really see how you'd lose backlight strength like the CCFL ones.
