Just the fact it doesn't show up on ebay means it's rare as fuck, meaning the price might skyrocket on ebay: the other day I had to give up on buying pic related, an item that doesn't even appear on fucking google images, because the price had gone too high for my taste (it would have cost me more than what I paid the camera). For all it's worth (i.e. nothing, that site has only a handful of reviews in it, which is a shame because it's an extremely well made site) on canonclassics the 100mm f2 is very well regarded.
