Yep, it's like most things. Anytime you want an example of something it will be unobtanium and/or outrageously expensive. Anyone not wanting one will find it at a pawn shop for less than the cost of an original magazine for it. That's why I diversified far beyond the K98k many years ago.......otherwise I'd be living in a world of poverty, frustration, and unfulfilled dreams.
Also, things that don't turn up are hard to price. It's market driven, literally. "Blue books" on such things are either way over, or way under, depending on what's going on in the market. Our respective opinions on the value of such things will be based upon whether we are buying or selling. At some point, for rare items, one must just pay, or not pay, based upon the individual "need", or while away our lives, and spend money in the search hoping it turns up for $500 less.
