I disagree with Maturin and think that you will have better luck collecting vinyl for older releases -- assuming they are in very good condition and not scratched to hell. For newer releases, one thing to consider is how the album was recorded. If it was recorded digitally in the first place, then you may be better off getting a CD or lossless download. Why get an analog format for a digital source? That said, there are some releases (e.g., Black Sabbath's 13) that reportedly have greater dynamics on vinyl, even though recorded digitally, because the CD/download mastering is so bad. (Yes, I keep coming back to the loudness wars. The world must know!) Even more silly is newly released vinyl that was recorded from a digital remaster of an originally analog recording. That's just absurd. An example of this is the new Beatles LP Box Set, which I believe used the 2009 digital remasters prepared for the CD reissues. Better to get the older vinyl pressed from the original analog tapes -- unless you like the beefed-up sound of the CD mastering, in which case, just buy the (much less expensive) CD instead.
By the way, Brothers in Arms was recorded and mixed digitally, IIRC, whereas the White Stripes, though more recent, recorded on analog tape.
