Please go to a RUNNING SPECIALTY Store. You will save yourself a lot of pain, and money by getting someone who is knowsledgeable to help you out. There is no one good shoe. I personally hate all NIke running shoes, because they don't work for my feet.
Things to consider when buying shoes, are your feet wide or narrow, do you have high or low, or NO arches, do you have bunions, do you pronate (if you are flat footed you probably pronate) are you runnign trails or roads, are you heavy or light, etc.
I personally love Saucony 3d Grid Hurricane. I ahve flat feet, with narrow heels and wide ball of foot, and I pronate. I also liket he New Balance 904's for my trail running.
