If the first question was answered with "yes", you should really think twice if it is a worth the money to get delivered 3 songs and some minimal changes.
Could the first question with "no" answer, congratulations, here the choice is much easier. Almost alone of the song "Devil's Hole Girls and the Big Revolution" it's worth investing the difference more in my eyes, otherwise you'd only wonder in retrospect whether it would not be better grasped the Special Edition.
2. To question this is purely rhetorical. It is criticized the poor quality of DVD. With conventional DVD quality this may actually not keep up, but how often did you look at this DVD for? Maybe one, two or three times ...
The DVD should not be a criterion of purchase decision.
The Cover is actually not what one finds displayed here. The best look at google times, because you will also find the cover of the "Special Edition".
For DigiPack itself can say "Standard DigiPack, beautiful to look at, quite decorative, but I imagine no CDs in the cabinet and then fixed for months the cover on. Of course it wirkr markedly precious, if you hold this DigiPack in the hands, it makes already what her ... but should not be the decisive tip the scales.
After it may sound at times quite negative, I should perhaps mention, why I still 5 star forgive.
Firstly, the music one more time is definitely a treat for fans. But here are schonmal least 4 stars due (bonus tracks included). And the DVD, a nice little addition as DigiPack On-Zop ... because you can then place the fifth star even without a guilty conscience.
