Who manages to get in-camera JPEG image files that you are pretty happy with? C'mon 'fess up!
I know a lot of the reasons why RAW offers much more potential for those who like and understand post-processing. Here's a link to an interesting thread that, though heated at times, unpacks a lot of the comparison between RAW and JPEG:

Still, even for persons who prefer RAW+PP, it might be unnecessary or inconvenient for some sets of pictures. So how do you (if that happens to you) get the best results from the in-camera JPEG? Which settings do you use to get what you think of as the best of the in-camera image development? Don't leave out which camera you are using, as some Pentax dslrs might offer more (or different) control than others or even better automatic in-camera processing than others. Also, what limitations do you find: is this less successful with certain kinds of exposures, for example?
Of course, any guidance in this area could help others still confused about or otherwise reluctant to go the RAW + PP route. Even for old slide film shooters who expect the exposure to be complete when the button is pushed, after which the processing isn't supposed to be fiddlly.
