Looking for Screenshot software

[Yakyb]

Im looking for a piece of software that (much like fraps) can take a screen shot on a keyboard press and saves the file automatically as the date and time the screen shot was taken

i would use fraps happily but im after something that takes sceen shots of the desktop

i know about prnt scrn and sniping tool but would ideally like to be able to save them with one button press
