Met I'm not exactly sure what you are looking for but have you looked at the 12x45 and 15x45 Zeiss Conquest binocs? I bought a pair of 15s last summer before a muley/antelope hunt in WY and they absolutely are GREAT! The 15s are about as large as I am comfortable holding without a tripod or prop of some kind. I continue to use them anytime I am sitting in a deerstand where I have long shots. For the woods I use a 9x40 Steiner Bighorn that works great. Ihave a compact pair of Optolyths that I use for bow and turkey hunting.

The Conquest series is VERY affordable for what you get and I am thrilled with mine. The Nikon Monarch series is a FANTASTIC set of optics as well, among the best for the money. As for the marketing wheres and whys, the market for binos over 12 power is many many times smaller than the more common ranges of 7-12xso it's just not in a makers economic interest to jump squarely into the higher power rangesfor such a small shareof the market. You might also want to checkinto Steiner, they also have some reasonably priced higher powered binocs.

Check em out,
