I've owned/used them all. Sitka for me.
Thinking about getting an OregonPackworks Bino Bro Pro. They get pretty good reviews. The Eberlestock one is getting crummy reviews because of its size. It's apparently rather huge. Biggest problem I'm having is convincing myself I want one of those things strapped to my chest. They look handy but I'm not sure I can deal with having to put my bino's back in there case every time I'm done using them. Dozens of hunters can't be wrong though, so I assume I'll get used to it.
