The tried and true: Linksys WRT54GL LINK
Ive owned and setup many (not because they went bad but because I moved) over the years and run DD-WRT on some. The one I have now covers my 3000+ sqft house and out to the street with great signal strength all around. Never had a problem streaming netflix to multiple devices (PS3, Oppo, Apple TV, etc) at the same time, nor any other issues in the ones I have setup at my grandparents or parents houses.
I had one of those and agree it's extremely reliable. I even had the longer antennae for better range.
