I replace my pads every 35 - 40,000 miles. I use the Bendix D862 I get at Schuck's Auto Supply (Parts America). They say they are a "lifetime" pad but I put on a lot of stop and go miles. The one thing to remember when buying pads is the real cheap ones will make a lot of noise. I have tried several different pads and brands and I get the best out of the Bendix.
