I'll start it off.
1. Under $100
I've never had any luck with scopes this cheap. I've always "inherited" these scopes when buying a used rifle with a cheapy scope and had them fail. A Bushnell on a 10-22 comes to mind.
2. $100 - $300.
I've had good luck with a Simmons Aetec and a Leupold VX-2.
3. $300 - $500.
I have an older Swarovski AV 3-9 that I traded for on a used rifle that still works very well. They obviously sell for more than $500 nowadays but I got a good deal on a trade about 15-20 years ago.
4. $500 - $1,000.
I have an older Nightforce that is very clear and has lasted for over 20 years.
5. Over $1,000.
I don't own any scopes this pricey.
