I have the Vortex Solo 10x25 ($55). My buddy works at the retail shop I got mine at an I had the chance to look through a bunch outside, mostly Vortex. First off, I wanted this monocular to do one thing for me. To be able to identify game from stumps/shooters from passers. I don't need to know how many eyelashes he has, just if I'm going after him or not. The pros of small and light weight outweigh the cons for me this year. After miles and miles of having big binos around my neck chasing elk in MT, I wondered why I even had them. You see game or you don't. Rarely do I really need to study an animal through the glasses. Granted, it is nice to glass hillsides for game hidden in the brush, but I don't do that often and if I want to I can still do it well enough with the mono.
As far as the models go the Solo's are the way to go. Offered in 8x36 10x36 8x25 10 x25 Its small enough to fit comfortably in my sitka hip pocket. Super light weight to give my neck a break. Half the weight of the Recons. The Recons are sharper, clearer, easier to spot with, but the start to get so large you might as well get small binos. Might be a good treestand mono. Again, if you like me and just need a quick identification on animals the Vortex monos are hard to beat.
