I think somewhere in all the advice is such that "if a wheel is thrashed or trashed such that the rim should be replaced, do so and then for goodness sake, use a new set of spokes to finish the job." I would only add to that a suggestion to just look for a new wheel or wheelset that is already built. Wheels tend to go on sale now and then such that a replacement wheel can be cheaper than parts to fix one... and a lot faster to complete. Second add is the suggestion to strive to always have a good set of spare wheels on hand...
