Funny, I've never had a problem with WB. WB is usually an issue under artificial light, but if you shoot in RAW mode you can correct it afterward anyway. If you 'always' have an orange cast then it sounds like something is wrong.
I get whites on the preview and after downloading, and I just leave WB set to auto. As an experiment, you might want to pick a white subject and try some WB bracketing. What you can't do, however, is pick a manual setting which will always work, because white changes under different lighting conditions and you need to compensate for that (hence auto-WB).
