I still have and won't sell my 8X42 BA's. I paid about $725 for them back in 2001.
Far more ruggedly built than the Swaro EL's and no history of fogging under alaskan conditions, unlike the El's. No way would I buy an El.
But, for me to buy a Leica BA, they have to be like new and warranted by somebody. You may well never need to get one fixed, very few have had to. But there is alwyas that chance.
For that reason, knowing how hard on gear I am, I'd buy new, probably a Cabela's Euro.
BTW, weight in a 10X is an asset if you plan to glass at extended ranges. E
