I'm getting an refurbished 360 from gamestop for about 0. I comes without a hardrive. Would it be better getting a memory card or the hardrive? The 20GB hardrive cost and the 512MB memory card cost . Which is better of getting? I also called one the gamestop stores and they said if i had a lot of sport games like for example MADDEN 09 and NBA Live they said that it would take up a lot of space and i wouldnt be able to save a lot of games on the memory card??? What should I get? Thanks for the help.
