Recommendation on a network extender?

[peekama]

I recently moved my file server to my basement, and I get very poor/inconsistent signal strength on the wireless network. I was looking for advice on a good model of network extender to remedy this.

Has anybody had particularly good luck with a certain make/model?

You can't go wired?

It wouldn't be practical. The house is two stories, plus the basement, so I think I would end up spending more on CAT6 then I would on the extender.
