Hey guys,this is my first post.
I want to ask some questions.
I live in Selangor,USJ 8

1.How much is a xbox 360 premium/pro?
2.Where can i buy it? (hopefully near where i live)
3.Does the xbox premium/pro needs an original game to play online on xbox live?
4.Does xbox 360 arcade is the same with Premium?
5.Do i need to install the games in the xbox 360? or play it like on ps2?

i heard it got a hard drive...i'm not quiet sure wat it is or wat its for...
i've seen soo many version of xbox
all i want is xbox live to play it with my friends and i dun have to use original games to play...

I NEED HELP
