This lot was collected from multiple sources. Some games are badly scratched and difficult to play or won't play. I have indicated the condition of each game below. 

All the hardware works excellent. See below for what is included and the estimated price for each. 

Hardware:

Silver Gamecube + Cables + Memory Card - $40

3 wired gamecube brand controllers - $75

1 Wireless Gamecube Controller with reciever - $30

Games:

Super Smash Bros Melee - Disc is fairly scratched but I was able to play it but can mess up

Super Monkey Ball 2 - excellent condition

Need for Speed Underground - excellent condition

NBA 2K3 - excellent condition

If all the games were mint condition then this lot would probably be worth quite a bit more. However, if you have a disc repair system you might be able to fix some of the games that don't work. I will take reasonable offers as I am not sure what the games should be worth.
