Xbox 360

[merck]

I was thinking of buying an Xbox 360 games console (with 60 GB hard disk) , but I don't really know anything about them.

In the UK, someone at the computer fair is a selling a chipped one + 1 game and various cables for £240. Is that a good price? Argos seem to be doing a non-chipped Xbox 360 + accessory pack + 1 game for £166.

Would I be better off getting a non-chipped one? Anything else to look out for? I read somewhere that Xbox live (whatever that is) will only work on a non-chipped console.

The last games console I owned was a Playstation I 10 years ago, so I'm a bit out of the loop.

Thanks in advance for any advice/info.
