This eats up batteries like crazy...is there a charger you would recommend????

Ros has a good idea. But my question is what kind of batteries are you using? Many batteries such as AAs are general purpose batteries and are not designed for the high energy use of digital cameras and the flashes they trigger. As such, I recommend using high energy batteries designed for digital photography. As Ros suggested, Varta is a good brand. They are usually sold in camera shops, are long lasting (because they are sold in small quantities) put out a lot of energy.

And, even though you think you've put in fresh batteries, underpowered batteries are just as bad. Even better, batteries with a higher mAh - like around 2500mAh would satisfy the higher power requirements of your camera.
