No one can fault your logic here. In fact, it is obviously foolish for anyone to spend more than is necessary to find satisfaction, no matter what you're buying. Of course, different people find satisfaction at different levels and have different tastes.
The other huge component in terms of FA vs. DA is sample variation. There seems to be more of this in the FA's than the DA's. This can make all the difference in a lens either blowing you away or underwhelming you. I am on my second 77. The first (MIJ, btw) didn't do much for me and I ended up selling it. Thank goodness I felt compelled to try it again because I adore the one I have now, which, coincidentally, is AIV. It is my favorite of the trio (and I have good copies of all 3) and will be with me as long as I shoot Pentax.
Sample variation, at the level it exists, is maddening and inexcusable. But it is a fact.
