Linksys, Netgear and Airlink should all work about the same. How big is your space, and is it all on the same floor? I'm a fan of the cheap Airlink's at Fry's. They work well for one story homes. For multistory homes, I would suggest repeaters, extenders or honestly powerline networking. I've found the newer g's to have more range than the older b's did. Sometimes signal is still flakey depending on the weather, time of day, etc.

I honestly never noticed a difference in reliability between Linksys, Netgear, D-link, Airlink, etc. I noticed a difference in price though!
