user196: Since mt.gox had to close its european office, is there any other exchange accepting SEPA transfers?
Sending a wire to the HK office costs much more than a SEPA transfer to me, and I'd like to avoid that extra expense if possible.

user7265: Bitstamp is an exchange located in Slovenia that accepts SEPA transfers.
SEPA deposits are offered at no charge, SEPA withdrawals cost 0.90€.

user5: MtGox and TradeHill usually offer SEPA transfers, but right now they are temporarily closed. MtGox is in the middle of a court case and TradeHill is changing banks (which should be solved in a couple of weeks). Here are some other options:

Intersango, like Gary Rowe wrote.
CryptoExchange launched yesterday and they charge a fixed $15 for any transfer regadless of the amount.
Bitmarket.eu. This is a peer-to-peer exchange so you must manually contact the seller to make the transfer. It is completely free to use and they have an escrow service in place to prevent fraud.
Bticoin-otc. This is not an exchange per se. It is an IRC channel where people trade Bitcoins over the counter. It is a fairly complex system (you must use a GPG key for authentication), but I'm sure you will find reputable people there willing to sell you coins. See this question for details.
CampBX is preparing a service to launch in Q1 2012.
Bitcoin Central. Charges no fees for SEPA deposits, but a withdrawal fee of €15.

You could use Intersango
It's a well-trusted exchange that operates within the Eurozone (and in the UK). You see their current fee structure provides SEPA transfer: 
Country             Accepting deposits  Processing withdrawals
GBP (domestic)      Free                Free
EUR (SEPA)          5 PLN (1.23 EUR)    5 PLN (1.23 EUR)
EUR (international) 10 PLN (2.46 EUR)   0.2%, capped: 9.5 PLN min, 180 PLN max
