The screens seem quite expensive. Better take your N9 apart, sell the parts (the USB cover, the shell, the soft cover, the battery and so on) on ebay or in here in the buy/sell forum, add some 50 bucks or more to the total revenue and buy a new phone. You can surely get more money for parts this way plus help a few people in here with spare parts too.

I paid almost 450 euro for my N9. if I was to buy and replace a screen for another 150 EUR (33% of the original price) this is what I'd do.
