Great glass for cheap never really happens in my world. You could pray for a pawnshop miracle, but I have personally never been that lucky. All the good binos I have seen were pretty pricey. They do however last a long time and you can look through them all day without discomfort. Euro brands like Zeiss, Swaro, Leica are on top. Meopta and Maven are the next step down. For an inexpensive good bino, look at the Steiner 8x30 (Marine/Navigator) these are very good and durable for the money, but might not fit your size/weight requirements. Maven has a demo/trial program where they send you a pair of your choice and if you don't want them, you can send them back for a full refund. This might be an option to get to look through them in person. I have eventually gotten really nice binos after years of selling and upgrading; mine are bino/lrf combos and I could not be happier. I have a connection for Swaro and Zeiss (Leupold maybe) that has really good pricing if you want. Cameraland (Doug) is also a good option, just reach out and he will give you special pricing under MAP (minimum advertised pricing).
