There are a ton of options, chosing one is like anything else, what do you want to do? To be honest, the best all around, redily available pads I have found are the Performance Friction pads at Autozone. Usually around $45 to $50. Love them on the street. Always had good performance out of them, even hot. They seem to disapate heat very well. Thet also seem to dust very little. I have them all of the way around my TTA and my F350 (4 wheel disc). I had a set of the standard Autozone Albany pads up front on the F350 for about a month as they were out of the PF's. I could not stand the dust out of them, so I swapped them when I had the chance.
Just my experience, your milage may vary.
