If you do purchase binoculars, test them out first in low light. Any pair will perform relatively well in good light, it's the low light that tests them.
I have a pair of Carl Zeiss 8x42 FL's, a bit pricey - but you get what you pay for. In lvery low light conditions they are one of the best.
Sturdy build, no chromatic aberration (check them against a high contrast object).
When you are looking at the high end of the market, it comes down to personal choice, how the bins feel in your hand, are they comfortable, etc. There isn't that much difference in quality between the Zeiss, Leica, Swarovski, etc.
I also purchased the Zeiss Diascope 85 FL, the only down side is the weight but the FOV and brightness far outweigh any weight issues. But I digress...
