How much is my Xbox 360 Worth?

I have a 250gb Xbox 360 slim. Comes with 1 controller, HDMI cable, 3 battery packs, charge and play cable, charging stand.

Games included:
GTA 5 (disc)
COD Ghosts (disc)
Blacks Ops 2 (disc)
Forza Motorsport 4 (disc)
Madden NFL 25 (disc)
GTA 4 (installed)
Madden 13 (installed)
Minecraft (installed)
Modern Warfare 3 (installed)

How much would all of this be worth if I were to sell it on craigslist?

175 to 200 you have some good games.

Well the console alone is about $100 and each game is $20-60 new so maybe around $200-220 depending what condition the things are in.
