I'm going to have to agree with Rainecloud here. I've seen working, good-condition N64 in shops selling for as little as $20. Granted, this is stirctly hardware, no cables or controllers, but if you have those left over from your old one, it should be fine. If not, it'll probably only cost $10-$15 bucks more, if that. And eBay is a great place to get things like that, as long as you've got a seller with lots of positive feedback.
