[Price Check] Xbox 360 Elite

I'm currently debating selling my Xbox, but I'd like to know what I could get first. I'm English so would prefer valuations in £, but $ is fine.
It's a mint condition blac Xbox 360 Elite, with all included leads (no HDMI cable), boxed, with all manuals etc.
Call of Duty:Modern Warfare 2
Call of Duty:World at War
Pro Evolution Soccer 2010
Need For Speed Shift
Gears of War 2
1 Wireless controller
Play and charge kit

 

does it have a hard drive?

 

From Argos it's 200 pounds brand new with no games. You can get around 150-180 I recon. (NO GAMES)

 

wrong section

 

Obviously it has a hard drive, it's an elite which means it has 120GB. I would like to know what I could expect for it all together.

 

Well the used Elite Console, meaning system, controller, hard-drive, cables and adapter - $180 is fair. MW2 + other games - $60-$70 is fair. I'd say around $250 USD total.
