That is an option. Sending it to Nokia for repair is also an option. Buying a second hand too (eBay Germany has tons of 'em). I'd seriously consider to not involve in 3rd parties and keep it under official warranty with Nokia. But it depends on how old your device is, how long you have warranty. Keep in mind S&H costs. I don't know any 3rd parties which replace screen so I cannot help you with that. Ich wuensche Sie viel Glueck.
