I know how it is. For several years, and this is no lie, I lived in a trailer court and mostly ate beans and fried potatoes, this was during my early married life while going to school. Then we rented for five years and were so happy we could afford to go to a movie or eat out. Then we got into a house, and about 10 years after that I could afford to buy a shot gun. Well, another 8 years has past and I could get the rifle and the scope.
Do the best you can do, stay with quality recommended scopes.
