New Balance is a good shoe, but I have always used Asics (I do run marathons). The GEL series always has a couple of $50-70 entries. What you really need to spend money on is insoles, get a really good pair(they will cost almost as much as the shoes) and they will last years. If you run 2 miles a day and your heavy(over 200lbs) don't keep your shoes more than 6-8 months(unless you really hate your knees). Then just move your insoles from the old shoes to the new.
