My local Blockbuster started renting DS games, so I'm thinking about renting Phantom Hourglass, and I'm wondering how much it costs. Anyone know?

I also have a poll on if I should rent it or buy it. Note that I don't have a huge budget for games.

Super Smash Bros. Brawl
Mario Kart Wii
Wii Sports

Also, a few from the GBA:

Advance Wars 2
Yoshi's Island

From N64:

Ocarina of Time
Majora's Mask
Mario Tennis
Paper Mario

Also, I own a near-mint NES, how much would that get?

Thanks for all your help, also, should I go to Gamespot or Gamecrazy to trade these in?
