For those that have gone digital (or trying)

[Lee Stone]

What titles have been roadblocks for you?
These are the ones that either have not (or will not) be converted to digital or are missing enough issues to keep you from switching over.

Mine are:
The rest of the Giffen/DeMatteis JLI/JLE
The Levitz Legion from '80s
The DnA Legion (and Legion Worlds)
Micronauts: The New Voyages (will probably never happen)
DC's Star Trek (will probably never happen)
Who's Who in the DC Universe
Who's Who in the Legion of Super-Heroes
Who's Who in Star Trek (will probably never happen)
New Mutants #35-38 (Always felt the Secret Wars II crossover made a perfect end-piece to the Sinkiewicz era)
Doctor Strange v1/Strange Tales (1987)/Dr. Strange v2
Thor Disassembled
Archie's '80s Red Circle (This was a new addition to my collection, even. So much much for making space...)

I have physical copies of the books I love the most. Other than Ultimate Spider-Man vol. 1 these tend to be Things I read and loved as a much younger me or things like Stan Lee FF/Thor, Wonder Woman and Superman archives that are timeless. I have no problem reading my friends digital comics for all the modern stuff. Two exceptions for modern books where I want the physical copy would be a hand full of Thor books and all of Mark Waids Daredevil. Digital is fine for almost everything that came out from the late 80's/90's on. I would however buy all of L.E.G.I.O.N. '89 reprints through Barry Kitson's run.
