If you live in North America, and dive mostly there and in the Caribbean (recreational not technical) you will be better served by a yoke rather than DIN by virtue of the fact that 99.9% of the cylinder valves you encounter while diving will be set up for yokes. Diving in Europe, Red Sea and parts of the Pacific plus technical diving would be DIN. A DIN to yoke adapter will work, but I wouldn't use it more than occasionally, in other words if you are diving where yokes predominate, get a yoke.
