The 1.7 50's are the sharpest of the three designs and have the flattest
field of focus, not as flat as a dedicated copy lens, but they're the
recommended lens for use with the Pentax Auto bellows, that is if you
can't find one of the dedicated bellows lenses of course.

not completely sure how to parse your question, but there are
certainly bargains on old equipment, essentially, in capitalist
terms, you look for inefficiencies in the market and lubricate them;
it takes some patience and a nose for quality; among the lenses i use
the most, my Macro-Takumar 50/4, SMC A 50/1.7, and Sigma EX Macro
105/2.8 (which i mostly manual focus) were all edge-market finds, and
the latter at $100 cost more than the other two together; you won't
find them at the prices i paid on eBay, but you might on craigslist,
a thrift store or a yard sale
I just found an A 50/1.7 for $45. I'm not positive, but if I'm not
mistaken, they've been going for a bit more than that lately on eBay.
Of course, if I had it, it would be my 3rd 50mm prime lens between my
K 50/1.4 and my M 50/2. Is the A 50/1.7 good enough to justify having
yet another 50mm at that price?

Don't lose heart! They might want to cut it out, and they'll want to avoid a
lengthily search.
