Try doing a forum search...many threads on this. Seems to break down to semi-metallic vs the newer ceramic ones. Less brake dust on the ceramic but more rotor wear (at least from what I have read). I need to do the same and am on the fence which way to go.
I like the HAWK pads they are very low dust and just an excellent pad. It all depends on what rotor that you want. You might check out EACeuroparts.com even if its out of stock they have them to you in just a few days. I always start with them and if they don't have what I want , "which hardly ever happens" , I check autohausaz.com or one of or other suppliers.
