If I was getting a spinning combo for $100-120 and only using it for bass, I'd buy a Shimano Sienna or Solstace for $30/40, and spend the rest on a good rod. And a good rod means whatever rod in your price range feels best in your hands. I used a Shimano Clarus(back when they were $70) and a Sienna 2500 for years with 10# PowerPro.
