I purchased a pair of Vortex Diamondbacks at the CLA last week - they are fantastic!
I spent ages on the Swarovski stand drooling over their binocs - truly superb - but walked away to think about it a bit before deciding to spend £1000+. Then down the row a little to the Sportsman Gun Centre and tried the Vortex units - amazing! Obviously not as good as the Swarovs, but for £115.99 they were amazing.
I have now tried them in the field and can highly recommend them.
