The delay you get, from the time you press the shutter button until the picture is captured is called shutter lag.
Five years ago it was common to have a shutter lag of one second or more.
Now, the average is about 1/2 second.
But you can find some cameras with shorter shutter lags.
Here are two Canon cameras in your price range with a tested shutter lag of 0.2 second.
Canon SD780 and SD940

They also have black & white and sepia color capabilities.

So I dont really know that much about digital cameras, but I want one that doesnt take forever to snap a picture. When my kids are laughing or I want to catch that special moment, it takes forever to take a picture with the camera I have.. I dont need all the fancy features, I just want to be able to take pics in black and white, sepia and color. I dont normally print big pictures.. any suggestions... my budget is under 300
