I bought the 10x42 Euros a couple years ago. I compared them to Pentax, Kahles, Swaro, Leica, and Zeiss in the store, outside Cabela's at dusk, and in the field.
Since then, I've sat side by side in all conditions/times with guys using the Pentax, Els, SLCs, and Ultra/Geo/Duovids...and have yet to notice a PROPORTIONAL difference between them. The Swaros looked a tad brighter; but I think it was because of the coating used. The colors just looked different, which made things stick out A LITTLE better....but not $1500 better...
From a binocular perspective, I have yet to be able to justify THAT MUCH more money for Swaros, etc. over the Cabelas Euros.
I highly recommend them, and with Cabelas warranty you can always take em back, no questions asked.
