How much would i get at gamestop for these things?

I have an older PS2, an 20g Hard Drive for the 360, the HD cables for the 360, Gears of War 2, NBA 2k9, Pro Evolution Soccer 2009, FIFA 2008, Madden 08, and Fight Night Round 3 (all for the 360), and the Xbox Live Vision Camera. For the PS2 I have 2...

controllers, Gran Turismo 3 A-Spec, The Sims Bustin Out, Avatar The Last Airbender The Burning Earth, Tonhy Hawk's Underground 2, Madden 2002,NFL 2k5, FIFA 07, Tony Hawk's Pro Skater 3, Onimusha 2 Samurai's Destiny, DBZ Budokai, Star Wars E. 3 Revenge of the Sith, Ace Combat 4 Shattered Skies, GTA 3, GTA San Andreas, MLB 2006, MLB 2006 The Show, All-Star Baseball 2002, Oni, Spyhunter, X3 the official Game, Jak 2, The Lord of the Rings The Fellowship of the Ring, The Simpsons Roadrage, Metal Gear Solid 2 Sons of Liberty, Xtreme Legends Samurai Warriors, FIFA 2004, FIFA 2005, NBA Live 2001 and SmackDown V.S RAW. What is a good estimate for what I would get at Gamestop or EB games for these things?

well today I sold a headset, GTA 4, Halo 3, and Tony Hawk's Project 8 and a 20g hard drive and I got $54. but I'm selling left 4 dead to a friend for $20 so I would suggest selling to friends or people you know

not much at all
the ps2 you could get around $20-$40
I dont know about the hard drive or cables
the 360 games you could get around $10-$30 each
the controllers you could probably get $5 each
all the playstation 2 games are around $10-$20 each
because all those things dont sell for much now, and your not going to get much at all when you sell them to someone else who then has to sell them

I honestly dont want to be mean but wouldnt it be easier to go to game stop and ask instead of sitting on a computer asking onlie people
