One more chime in that, if you are going for the premium price features (i.e. 802.11n right now), then the AEBS is the best option on the market. I have an 802.11g AEBS that I purchased about four years ago. It's lovely. Besides having been by far the prettiest router on the market at the time, it's easy to use, rock solid reliable, and always been ahead of the curve technologically (e.g. it was worth its price at that time because it has a USB printserver; it had WPA well before this was not commonly available, and also updated to WPA2 long before it was generally available). I got my parents a Netgear 802.11g, and it works, but it's nowhere near as nice.
If you're going for G, as others recommended, there's nothing wrong with the majors at this point. But once you get to N, no one's routers are all that cheap, and Apple is worth the cost.
