Metroid and Memory Card??

okay i just got a wii and so far im getting a little bored of it. I already beat Zelda and a couple other games, but now i want to try out some gamecube games. I really want to get Metroid but i'll need a memory card first (which sucks). I was just wondering how much do you think that'll all cost. Metroid Prime with memory card.

Thanks for the help!

no more than $20, you can get metroid for like 10 now and a cheap memory card can be any where from 5 - 10
