I have used the Leupold wind river cascades in 10 x 42 for a few years now and really like them. I have a full size set by Nikon that is good also. Either manufacturerer puts out some nice glass for the money. I compared the cascades side by side with Zeiss and Swarovskis at 3 to 5 times the price but could not see enough difference to justify the price. Even in low light conditions there just wasnt much difference for me.
