Recommend a good wireless range extender?

I'm looking for something cheap that will make the signal stronger on my router. Something like this but hopefully much cheaper.

It plugs into an outlet and connects to the router while the other plug goes into the room with poor signal. I need it for my PS3. Thanks to all who reply.

Have you tried constructing a DIY Pringles Yagi Antenna? I got an extra 400ft from mine, using an old dish satellite.

I've read about it on consumerist.com and I might end up having to try it. I like to keep things neat though. Thanks for reminding me of that.
