I just bought these not too long ago: http://www.amazon.com/gp/product/B002SOU2Y0 http://www.amazon.com/gp/product/B002SOU2Y0 I've been happy with them so far. I also like the fact they use standard NiMH AAA batteries, so replacements are cheap and it's easy to keep a spare pair around. I'm able to wander around my apartment with no signal issues.
