* for a rental charge (at least the last two I've had were this way).I'm not sure how useful an Airport router would be these days. I loved the ones I had; they were really reliable. But now nearly every ISP gives you a decent wireless router for free.
I had the AirPort Extreme and found it rock solid and very easy to administer. I also got a ton of usage out of the AirPort Express -- I used it to turn a pair of powered bookshelf speakers into an AirPlay setup, which was awesome.
