any ideas why? I bought a set of 8x42 SLC two years ago, they were $1750 at Cabelas. Last year the price went up to $1800 for the same pair. I see them today for $1550. Just wondering if they are coming out with an update or why the prices dropped. I can't remember what the 15x were, wondering if those dropped in price as well. Been thinking about picking up a set of 15x SLCs for a little while...
