The biggest problem that I have with the FA 77 is that I don't have a full frame camera to shoot it on. It feels too long for APS-C and I actually prefer the DA *55, although that is plenty expensive in its own right. Anyway, there are plenty of reasonably priced primes out there, particularly if auto focus isn't crucial and many of the older ones have interesting, special rendering which today's more bland lenses don't have.

I think it is important to understand the difference between primes and zooms. In general, the benefits of primes are : smaller size, faster aperture is often available, more resistance to flare, better rendering of out of focus areas, and they will usually be sharper at a given aperture than a zoom lens at the same aperture. Obviously, if you are able to stop down to f5.6 or f8 (there is enough light to do that), your differences between a zoom and prime will shrink, particularly if you are not printing large or pixel peeping.
Obviously, not all primes are equally expensive -- the FA limiteds are currently the most expensive of the Pentax lot at present and I don't know if for current prices they are worth it. I do own the FA 77 and it is prone to purple fringing, but it is so easy to fix in post that it isn't a big deal. Truthfully, the list of Pentax lenses that are prone to PF in my experience is pretty long and includes the DA *16-50, DA *200, and the 100WR. It just isn't a reason to like or dislike a lens any more since you can fix it with a click of a dropper in lightroom.
