Recently I found an old FLGS that still has the first Dark Sun Campaign setting boxed set and is selling it in it's original shrink wrap for the release price from '91. Now I'm wondering if I should get it as a collector's item. I have no clue if it's worth anything though. Do you believe it will make me rich? 
Edit: Also, what sites do you use to find out if an old rpg product is a collector's item?
