I currently have a Gary Fisher Tassajara, a genisis frame hard tail. I am looking to replace my old Manitou Magnum fork. I don't have much cash(read about $100 MAX). I was looking through the usual websites and I saw the Rock Shox Judy SL U-Turn for $99. Would this be a decent upgrade from my old Manitou? Would it fit the geometry of the bike? Any others in the price range I should be considering?
