Mine is similar to that little one from Stanley, but not exactly the same. For 38 bucks, I may upgrade! Those larger ones are still pretty compact when "folded," but consider weight too. As to optical quality, I agree--the cheaper ones are pretty PC-poor.
My seachest 'scope is the 18-incher. You might want to note that the larger ones have a sunshade built-in. That's handy on these things. I noted that if you spring for the huge one you can get it with "patina." Too bad that's not an option on their other ones.
Anyone know when binoculars came along? The Stanley brass/leather in-line prism ones look like they just might be a bit better for modern eyes. But PC?
I still like my little one for size/weight though.
