I think the best value in that price range would be a Swift 3-9x40.
They are super rugged and clear with a lifetime warranty. Never had a swift fail on me or any of my friends and relatives that use them. They're mounted on everything from .22's up to 300win mag's and 7stw's.
A couple of my neighbors got rid of their Leupolds cause they think the swift is better
I dont agree with that, but they are pretty close in quality for a fraction of the price.
A little more than your limit of $100 though at $109 shipped
