eh... if you go ebay, it's probably anywheres between $20 - $50 depending on who you buy it from. If you buy it off the shelf at your local Electronics boutique, it'll probably definately run you between $40-$50
Warez is a hackers site. They crack games and give them out for free. Hardly worth the time and effort that you'd go through to put all the files together to make it all work, I know, I've done it before. it's easier to come up with the $50 bucks.
