Actually Classic Star Wars was a run of reformatted reprints of the newspaper strip that ran from 1979 to 1984. It was originally just the later Al Williamson strips but later on they would go on to reprint the early Russ Manning strips. You can see more by clicking on my sig.
The only Marvel reprints Dark Horse has done as far as I know were first the film adaptions and then later the omnibus books. I believe they plan to do another run soon including some of the british stories that were left out the first round.
