Well for sampling I agree, you can find tons of vinyl for cheap, but not all vinyl is equal. For example, I picked up Tom Scott's Honeysuckle Breeze some years ago for about 20$, and then resold it on e-bay for 230$. Or buying a reggae single for 1$ and selling it for 100$. There is value for everything, but it depends on the market, buyer, and their desire to have something. I'm very selective when I buy stuff now, and some of it is not easily found for cheap, so sometimes I have to pay more for something.
