I never had a Simmons. I have had low-end Bushnells and have not had problems with them. My son has the low-end Nikons and loves them. I have a Redfield Revenge on an Optima. It is OK but you have to stay familiar with the accu-ranger crosshairs. Sometimes you can find a Leupold VX-1 on sale, I have $100 invested in a "blemished" 3X9X40, they are great scopes. Keep in mind that a fixed power scope has less to go wrong then the variable power scopes.
