Hello. I'm working on collecting original prints of all of Hulk's individual issues barring the mega-expensive ones (Incredible Hulk 1-6, issues 180 and 181, etc.). I'm mainly collecting the Hulk books where the Bruce Banner Hulk is the main character (so I'm ignoring most of the Red Hulk book), but the Banner Hulk does feature prominently in some Red Hulk issues and in some other characters' books and some event books. Since it wouldn't be practical to collect every single appearance of his, what one-off Hulk books, guest starring appearances, and event books would you say are critical for the ongoing story of the Banner Hulk? Thanks in advance for the help. Just don't want to miss anything.
