Does anyone else set a limit of like 20 bucks when buying a cd? There's plenty of stuff I'd like to have a copy of and plenty of stuff I will have a copy of... but I really dont need to go out of the way to buy a "centerpiece" to my collection, and if I get one, I sell it off to buy more.
I've applied this to pretty much anything I've collected over the years... band shirts, cds, baseball cards, mtg cards, etc... and I've been fairly lucky with ending up with things that are worth money over time. (or even shorthand, shit I bought a pack of yugioh cards once, pulled a first edition red eyes black dragon and sold it to a dealer from between the rest of the cards in the pack for 60 bucks, and went to the rest of the card show with triple what I started with)
Edit: I suppose what I'm saying is that I collect things for purely my amusement, not for monetary value. I'll leave that for the shiny things my fiance likes.
