i own 3 pairs of Nikons and have looked thru a ton of glass over the years .
i dont typically worry much about my glass as they dont cost tons of cash .
but they are durable and will pull in detail quite well .
that all said you wont likely find really suitable optics for much under a 100 from what i have seen .
there are cheaper ones out there and burris and leupold and on and on make good glass to .
50 objectives are a must for me in low light conditions
that is something i might add as a tip on a bino purchase .
more compact glass dont gather as much light .
