Kraken.com is an another very good euro exchage. And is bit easier to get into. I mean the verifications...
Kraken has bigger volume than Bitcoin-central.com
But do they offer the same garantees as bitcoin-central in that the admin won't leave with your money of bitcoin? This is not rhetoretical question, I don't know.
I used to use Kraken for all of my euros before I discovered bitcoin-central.net doesn't charge for transfers (like bitstamp and unlike kraken).
Regarding the UI, they definitely have the most interesting one, I'll grant you that.
