As some of the members mention, if you can not afford $150 to $200 for a camera, wait until you can. Cheap cameras are a hit and miss, resulting in quick failure, poor quality pictures, or hard on batteries to name a few. The reason the price on some cameras are low (cheap) is the manufacture has not put good quality parts in them and also may be trying to under cut a company that is making good cameras but due to their quality, the price has to be higher. Check out the quality of pictures or videos submitted on this and other forums to see what you would be satisfied with. Check:
