The Airport Extreme is good, no denying that, but there are better and faster things out there that cost less. Don't look at the marketed speeds, they are nowhere near what you can actually get. 600Mbps for example requires 4 spatial streams and a 40Mhz channel, which is something almost no client supports. Most standard clients do only 1 spatial stream which gives you around 150Mbps theoretically. My laptop and router support 2 spatial streams and 40Mhz, which resulted in a theoretical maximum of 300Mbps, though 100Mbps is all I get from it.

If you want something flexible - go for one of the cisco e4200v1's and stick dd-wrt on it - been very impressed with mine! Do avoid the v2 though - it does NOT support and third part firmware.
^ that. Though I strongly prefer Tomato firmware, it's much lighter and has a cleaner interface.
