The only overpriced Thing I bought was the Collectors Edition for the latest Re-Pressing of Conquerors War.Cult.Supremacy. But to be Fair, it was to LPs, a Shirt, Patch, great Inlay, LP-Cover as Flag and Poster, for 50 Bucks, so I guess it was k. Most other Stuff I have, I get on Flea-markets, most People don´t even know what they are selling there. 4 Euro for a first Pressing of Iron Maidens Killers...

Was it worth it?

There are really two factors for paying a bunch of money for a record: you either really love it, or it's really rare. In my case, it's both.

The record was pressed only 1000 times in 1998 - and only one time. It's one of those great underground hardcore gems.

I like to think it is. It was released for record store day a few years back to a very limited run. It is a good covers album but I wouldn't say it's my favorite album.
If it's your all time favorite album then I don't think you should feel bad about spending money on that album no matter how expensive it is.
