I've had real good luck with Linksys' new flagship Wireless-N model, WRT600N. My friend sets up high-end consumer networks for a living and he advised me to get a Wireless-G model as well. But I read up a lot about the pros and cons of a Wireless-N network and decided the new WRT600N had just what I wanted. I bought the WRT600N a month after it was released and haven't had any problems with it yet.
I love having two seperate wireless networks in the home from one router: a Wireless-N only network on the 5GHz wide-40mhz channel and a mixed b,g,n newtork on the 2.4GHz standard channel. My Dell XPS M1330 connects great with its Intel 4965AGN card to the Wireless-N 5GHz network and I get incredible reception and network speed (which I need since all my data is on an HP MediaSmart WHS). I also have a Linksys DMA2200 Media Center Extender that connects to the Wireless-N 5GHz network. This allows me to stream HD content without lag to the living room on the other end of my house. The standard 2.4GHz wireless network handles my older devices including a couple Dell Axim X51v's.
If you go Wireless-N, I'd highly recommend the WRT600N or another dual-band router. The old Wireless-N routers like the WRT160N only operate on the 2.4GHz narrow-channel, which severly cripples Wireless-N's abilities. As far as compatibility is concerned, if you're buying N-products, make sure to read around on the net to see if others have used the products you are planning to use together (or buy products from the same company that are designed to work together). Once you get a Wireless-N network set up properly, there is no going back to the backwaters of Wireless-G.
