Rotterdam,
I use European Sea Sports everytime I'm in the Marmaris / Icmeler area of Turkey. I know the owners and it's an excellent dive centre. As lynwestie mentions, they used to be called European Dive Centre but changed name and dive sites in 2007 and now operate out of Defneli, a picturesque area towards Datca, about 45 minutes drive from Marmaris. I did my Rescue Diver qualifications with EDC about 8 years ago and found their training to be excellent.

Like all sports, there's inherant risk involved. However, with good training and experience, scuba diving is a safe sport. You might find the following post useful:
