I've got my sights set on the Three A figures, they're kind of pricey, but gorgeous. And yes, I would definitely recommend the old Eagle reprints if you want to get into Dredd, the Dredd Crime Files more specifically

Newer Dredd in 2000 AD kind of lacks the pure grit and rawness that the original had, almost like a punk rock concert in comic book form. There was almost something magical about the pure anarchy 2000 AD's writers and artists exibited back then, it almost seems kind of like a lost art these days
