Having a sealed Vault 10 is great and all, but nowhere near as good as having that show blasting out of your speakers at top volume. Sure, a record loses monetary value once you unseal and play it, but it gains a whole lot more in the process...I don't collect vinyl records, I collect the music that's on them.
And while have had no joy with TMR random lottos, if ever I do score a limited release I'll be playing it (unless I don't particularly care for that one, in which case I'll be looking to score a trade for one I do care about).
Point is, collect away, but don't lose sight of what it's all about, which, for me at least, is the music.
EDIT: DRAT! New page makes post look like a non sequitur.
Crap, I started collecting posters.
