There is also a newer model, the L4000, that is about $10 more expensive that has a Lithium-Ion 2-cell battery. You can differentiate this model by its color, green and silver. It has a slightly larger capacity of 2200 mAh.

Thanks! I didn't notice the scuff covers until we noticed the poor quality of the photos. After I took the back off and removed the film covers, the photos are back to the original quality. Thanks again for your comment. The covers should have an obvious tab on them for easy removal
