Transfer your Bitcoins to Bitcoin.de
People buy your bitcoins, your bitcoins go into escrow at Bitcoin.de until you provide your bank details to the buyer, the buyer wires you the money and once you confirm you received the funds then Bitcoin.de release the Bitcoins to the buyer.
Takes around 48 hours to get your money but with the least amount of risk involved. Also Bitcoin.de are not acting as a Money Transmitting Service like the other exchanges so they're not going to end up getting raided, also Bitcoin.de are a registered business with an actual location unlike BTC-e & Bitstamp.
Bitstamp is gaining more volume atm but if you use them you're fucking mental! They as based in Slovenia and have their business address listed as a mail forwarding address in Reading, UK. Plus they have WHOIS privacy protection on their domain, yeah really trust worthy and transparent!
You'll get paid in ?s though, make sure you have a ?s account so you don't get fucked in exchange rates though
Or you can use Mt Gox and wait for an indefinite amount of time, SEPA transfers are taking over 30 days. They're talking bollocks, they have serious liquidity issues and are lying about it!
You've got a couple of other options that have been mentioned in this thread, I wouldn't wanna trust a 5 figure sum to BTC-e or Bitstamp
