I would say that these 027 have been selling, in different states of disrepair, well under the $1000 mark, and that those in reasonable good shape went for around $1000-$1200. Recently (asked) prices have jumped, but I don't know if they are really sold or if we are constantly watching the same pieces in different ads.
In any case, I would never say that these 027 are plentiful, and I have never seen any of these selling dirt-cheap, as some other member said, so maybe I am missing something. A problem may be that without size references, the ladies sized ones look strinkingly similar to the full sized 027, and maybe that is why some people may have seen some SM 120 selling for around $300 (if $300 is deemed dirt-cheap nowadays).
