I regularly see Mint- M4-P's sell in the $750-800 range, retail at the
camera shows.

A low price, but an older screw mount lens with the M adapter,  which
has two frequent problems:

	1) a VERY soft front coating which easily scratches even from careful
cleaning
	2) original sperm whale lubricants which often degrades and migrates to
the
	   lens elements, creating a "haze" or "fog." 
	3) some people are lucky enough not to have encountered the fog, but
they
	   are very lucky IMO.


The way to check for either is to shine a small bright flashlight
through both ends of the lens.  It should be crystal clear, if it is
not, you have problems.
