What is the cheapest best camera

There is no such thing as "The cheapest best camera", you can get the best camera in the world for free. It depends on the seller.

What I think you mean is which brand of camera is high quality but has the lowest price. That would be Kodak digital camera. Kodak, Canon and Nikon sell cameras that are good quality and reasonably priced and they also sell cameras that are good quality and have features that increase the price dramatically. When you buy a camera and use it you will become very familiar with its limitations and when you go shopping for another camera you will see cameras that will do things your camera cannot. My Kodak will take good quality photographs but I must wait several seconds before I can take another photograph. So I am looking for a camera that can take 5 photographs in 1 second.
