Orlok - excellent selection, and wide ranging.
'The Stand' - not sure whether the revised version is better though, unless you're a King afficionado - & 'The Road' would come near the top in most similar lists, I'm sure.
(Would 'The Dark Tower' series qualify, I wonder ?)
The Ballard, Shute and Wyndham wear very well - I got away with being caught reading 'On the Beach' well after lights out, by telling my Dad it was homework, I remember.
'The Road' simply kept me glued to the page with only minor forays away for non-essentials like driving, cooking and work - but I managed to do a bit in the kitchen and workplace, admittedly.
I have been given a copy of 'Resurrection Day' by the improbably named Brendon DuBois, but haven't tackled it yet, so withold judgement.
I confess I like my post-apocalpses recent, rather than unknown civilizations or "Terminator" scenarios - I like me ruins recent, and recognisable I suppose !
I must have a think and a rummage when I get a bit of time - I'm tackling George R R Martin at the present week/month/year, which is becoming a bit of an epic undertaking in more ways than one !
