I'm leaving for europe in two weeks. I'll be there about 3 weeks and I'll be taking along my d50 and a point and shoot. Both have rechargeable batteries. What is the best option for keeping the cameras working? extra batteries some type of converter euro charger other? This is my first trip to europe and I'll be backpacking and I dont want to miss any shots because I dont have any power. Any recommendations for what items to get or where to buy would be helpful.
