I've never had a D-Link router or switch die on me, and I've bought a lot of them. they're peripheral items, like USB wireless adapters and the like are utter crap, but for routers, switchs, hubs, and kvm's, they are reliable in my experience. they are usually $10-15 cheaper than a Linksys as well.
I like Netgear's blue metal cased stuff, though their silver plastic boxes suck.
A lot of people buy Linksys for the Cisco name, and because they can flash firmware on some of the wireless routers. i don't really care about either, and in my experience D-Links are just as reliable. Hence I buy D-Link.
