Free: Contests & Raffles.
Go to Cabelas, Sportsman warehouse, etc and try looking thru a bunch and see what you might like then go shopping
Most binos look good or ok in the store. Go to the store at dusk and pick out the ones that you like, then ask the person behind the counter to bring them one at a time outside and see what they look like when the light gets low. For example, I have a pair of Nikon Premiers and my buddies have the Nikon ATB's. During the day there is not much difference, BUT I can glass at least a half hour before they can at sun-up, and can glass longer than them at sun down. During low light is where you see the difference between the $500.00 and $1500.00.
