Hard to recommend these kind of binos without looking through the very one you intend to buy.
The reason is that top brands tend to have a pretty thorough (multi step) quality control so there is very little difference between each single specimen.
By that I mean that if you have looked through a (say...) Leica 10x42 you could confidently comment on another Leica 10x42 .
With house brands and generic brands (like the Hammers) you could have 10 of them and get 10 different levels of quality.
Essentially at the end of the production line binos are graded and then labelled according to the re-sellers specs.
The best stock goes to the best customers (volume and or price)
Whatever stock is left is sold to cheaper brands.
So if I had a Hammers 10x42 I could not tell you how good or bad yours will be.
