I'm trying to spend the LEAST amount of money I can. I want a digital camera that has a nice display on the back to review pictures I've taken. There are 50 thousand digital cameras on ebay. Which camera is actually worth buying for a really low number? I'm sure there are certain cameras in the low numbers that you guys would say "not worth it, for $25 more could get this and it would be worth it". Show me that camera! All I need it for is to take pictures to put items on ebay and the occasional vacation etc. Thanks!
