Proprriotory batteries vs AA, want a G9 but...

Greetings all,

I am interested in the G9 but it uses special batteries. I live in europe and do a lot of travelling. With AA's if I run out of juice, I can buy batteries at the corner store, but with the propriotory batteries, first they are expensive and you also have to carry spare(expensive) batteries and charger. And if you run out of energy, you're stuck. What are your experiences? Thanks, Lepewhi
