Dub - Hells Bells is such a great record that I plopped for the Pure Pleasure reissue. It's not a super-great sounding LP (strictly from an audio quality point of view), IMO -- but it ain't bad either. Somewhere in between. So I would not recommend buying it if you're in the game for an "audiophile experience"; HOWEVER, I would definitely recommend buying it for the music. Even at the expensive PP price. (OTOH, if you already have the Charly CD, it's probably not necessary.)
Steadfast isn't quite on the same level, IMO. It's good stuff, but not as good as Hells Bells.
My 2 cents.
