as i suggested before... the used market isn't a bad thing; where you can get possibly great deals... (i guess id just ask the owner to take some costom photos of parts... (running under its own battery w/out being plugged in... lens condition... lcd condition, and current picture quality by making a costom shot for you)
something like this 8mp sony Cybershot F828 is currently a great deal for the time being @350... and EXCELLENT night shots... its actually the next step up from my first camera, the F717
