I have/had both Linksys and real Cisco hardware and very happy with it. No experience with your particular model, but the good old black and blue Linksys
APs, and
routers, and now a flashy
Cisco accesspoint, and not for the looks, because all the networking hardware is in a place where I hardly ever see it anyway.
I'd go for the Linksys. But the Netgear one seems decent too, just don't have any experience with them, but looks good from the info on the site. Wouldn't pick the D-Link, doubtful how well integrated antennas which can be turned to a preferred position preform.
