One thing to note, is that the Boker TS series folding hunters are an international product. Parts are Chinese, finish work is done in Germany. How much is debatable, but it's enough to get a "made in Germany" designation. They are like high quality Rough Riders in looks and finish. That being said, they are nice.
Case's '65s are still pretty good. Three things to look out for are - Loose shields, the famous Case edge burr, and occasionally light side to side play.
The Case is a bit stouter knife, and most tend to prefer the '65 handle shape better. The little turn at the butt makes for a nicer working knife. The Boker's "Yukonish" shape is a looker though.
If you find yourself looking at single blade versions, you might also try chasing down an old stock Schrade USA 125ot. The simple linerlock on it makes for a nice, stout knife.
The Cold Steel Ranch Boss 2 is very, very stout too, and carbon steel.
