Just a suggestion.
Years ago i wanted a pair of binoculars to take to a concert.
I checked with my local rental yard and found they sell their equipment after it has been rented for a given amount of time.
Now, this has been more than 30 years ago, but I bought a used, but in fantastic shape, pair of Minolta binoculars for $30.
I still have them today and they are fantastic, especially for $30.
