Joe, as Jim has said, a router is a router...except some are better than others. Some offer better signal strength, some offer much easier configuration.
I'd plow through the reviews at newegg.com and at Amazon - get a clear idea of what people liked and didn't like and pay particular attention to the percentage of buyers who gave the router 1 star/egg and WHY they gave it that rating.
That D-Link is undoubtedly the cheapest wireless-n router I've ever seen ($22 at Amazon) - just not sure it's necessarily the best.
For ease of use, with good signal strength, the Apple Extreme base stations are definitely tops, but they are also considerably more expensive. However, after bashing my head on the wall over many years with various cheaper modems, I decided to bite the bullet a couple of years ago and bought the Extreme and haven't regretted it. However, we also typically have 4-5 networked Macs, a PS3, an iPod Touch etc. in the house, over 3 floors - so it was well worth it.
