It's not a router, but I recently purchased a D-Link DGS-2205 ethernet switch to replace my ailing Cabletron MR9T-E (which was top of the line when it was manufactured by cavemen 25,000 years ago).
The D-Link was refurbished, purchased directly from the D-Link online store. Great price, and it shipped out almost immediately, arriving at my doorstep in 3 business days. There is no way you'd ever know it was refurbished, as it is in perfect condition. It is 5 port, which is fine for my tiny home network (my gaming machine, my wife's computer, an old battered HP we use as a file server/dump, and the occasional odd laptop.
It is, as one would expect, simple to install and set-up, being a simple switch. A crossover cat-5 from the modem to the switch, then cat-5 to the computers, and that's it. It auto-detects traffic and sends it where it needs to go.
Of course, a comparison to the old MR9T would be unfair, because it's comparing 10base apples to gigabit oranges, but here it is anyway: this thing FLIES! Intra-network traffic sails through the cables like a formula one care driven by cheetahs. A file transfer that would take the old MR9T 5 minutes goes by in a matter of seconds. Internet speeds haven't improved, unfortunately, but I have to blame that on my ISP and my also ancient Actiontec DSL modem that currently doubles as a favorite nap spot for a cat on cold days (oddly enough, cats don't improve heat dissipation on electronics, ruining my plans for a cat-cooled gaming rig).
The final feature of this surprisingly feature-ful (it is a word because I say it is) switch is the power saving feature. It automatically cuts the power to unused ports, saving the power that would otherwise go to them. Probably not a huge power savings, but every little bit counts, right?
Long story short, if you need something simple and relatively dummy proof to hold a small home network together this is a great way to go.
