I am getting a digital camera in like 6 days, but i havent made up my mind yet on which one I want! I either want the Nikon Coolpix S51 or the Nikon Coolpix S52. My parents are willing to spend at the most $180.00. (which is okay because at walmart the cost is $159.99) My first question is what is the difference between these two cameras? they look exactly the same! is it that one is 8mp and the other one is 9mp? My second question is where can i find a red or a green one that is under $180.00?? ( at my walmart they only have a blue one) THANK YOU SO MUCH!!!!! :)
