Found a Nintendo 64 console bundled with 1 controller, WWF No Mercy, and Goldeneye for 49.99 at Goodwill today. Went to a second Goodwill and found a second controller for 3.99. I'm pretty stoked. No Mercy is one of my all time favorite games, and Goldeneye is pretty fun too.

Bought that case from Fry's on clearance for $5 a year ago. Best one if you can find it.
