Don't buy a camera because it's expensive and high-tech, promises lots of features and is really cool looking. What's more important is for you to decide what you really need in the Camera. Some just need a manual focus, that can be found in a basic home cam, you just have to specify the same to the seller. Some just want to shoot videos for memory... even an iPod Touch 4 would do for that!
So what's really important in a camera is your primary, and perhaps only, requirement. Trust me - you go on buying a really big expensive camera, sometimes you won't even be able to understand how to turn it on!
So there you go. Function matters. That's all.
