Picked up some from Half Price Books for a buck:
Tangled Web 1-3,5
Spider-Man/Power Pack 1-4
Marvel Knights Spider-Man 3,7
Spectacular Spider-Man (v2) 4-7
All for a buck, all filled in holes in minor runs. I’m excited about the Power Pack stories. Back in Junior High or so my friend Russel had some Power Packs that I never got in to, but I’ve liked some all ages Spidey lately, so I’ll read those first while the rest gets archived as I slowly make my way through Spider-History.
