I would look at the Bushnell Banners. I sold a ton of them at a gun shop I used to work at and it was a rarity to see one come back. More than half went on 12 ga slug guns which are pretty punishing on the scope and shooter. One of the least expensive places is The Digital Oasis, free shipping. My last order from them was yesterday where I ordered a Zeiss Terra 3X 4-12x42 for 366.38, no one else came close to that price.

Simmons was a complete different story, problems, problems and more problems if they were on any thing that had recoil.
