I have an Airport Extreme (supports Wireless a/b/g/n) router for sale, in very good condition. It'll come with its original booklet, discs, and box.
This router has been reliable and I've never had an issue with it. Don't have use for it any longer as I've switched to a Time Capsule. These routers are truly 'extreme'- they're incredibly fast if you've got an n-capable Mac, and very sturdy. They couldn't be easier to setup on a Mac or Windows, and blow the rest of the competition away in terms of range. I've been across the street, (several hundred feet) working on my laptop at a park bench without issue!
