well i dont know exactly what singer offers and what the price difference is but yeah the ho alt. i suggested the interstate deep cylce because will help some while at stop signs/lights since the car will be at and idle. then if you feel like its needed a xs power battery later down the road to replace the interstate then sell the interstate or keep it as a spare battery incase something goes wrong. or you could just add an xs power battery to the trunk later down the road. your choice.
