Xbox 360 Advice

Alright need some advice on what to do next,
I've got a *Falcon* 360 Pro I bought some time ago. I haven't really had any problems at all with it so far.
I got a £200 voucher*
But alot of people urging me to purchase a jasper Model Elite.

Should I sell the voucher and buy a 120GB HDD, + couple of games.

Or should I buy a Jasper Elite with 120GB HDD and get free halo ODST.

What would be best for me to do.

 

Depends what the games are on the first category. If the games suck dick, it wouldn't be worth it. If it's like... Call of duty, L4D, and GTA, you know, decent games, then take that. If not, ODST is worthwhile strictly only for campaign and firefighter. Don't know if that interests you.
