Me too. Using the kit lens as a focal length test bed is a good idea, because normal is not the same for everyone and is not simply the result of a math formula.
As for the lenses, I think the FA 35/2 is really very good for the qualities listed, sharpness and color rendition. I think it matches the K35/3.5 for sharpness and is much better than the other f2 lens options from Pentax and Takumar. If you can get this lens for close to its price before it was discontinued, $300, it's a good deal.
I've never used the FA43 but the FA43 is probably better, because it was built to be better. Build quality and feel are certainly better. I think the biggest reason not to get this lens is focal length not meeting the normal needs. Price is also an issue.
A third option is the DA 35mm f2.8 Macro Limited. That has all the great Limited features, including high price, but adds 1:1 macro and takes away one stop of speed.
