Nexus 4: 8 or 16GB?

I don't need the extra 8GB, but I'm debating spending the extra $50 for resale value a year or so from now.

Biggest question is...will the 8GB take a hit that's larger than $50 on the back end? Or will I make up some of that $50 difference when I go to sell it? It's anyone's guess. What do you guys think?
