I have no (zero) personal experience with Sigma lenses, but I did come
across a book on macro photography not too long ago that featured a lot of
photos taken with their 70-300 dl macro (even the photo on the cover, for
instance). They looked pretty good. The author of the book seemed satisfied
with that particular sigma lens.
Looking the 28/1.8 up on http://www.photozone.de/ , the people who used it
rated it thusly: perf. wide open: poor; perf. stopped down: good;
vignetting: critical; distortion: significant; color cast: slightly warm;
flare: quite heavy; optical perf.: sub-average; build quality: good. People
at http://www.photographyreview.com/reviews/35mm_lenses/product_4728.asp
really think it is something special. Looking at KEH, used Pentax manual
and AF 28/2.8s are going from $70-$170 (ranging from bargain to like-new,
minus).
I guess it all depends on your expectations
Good luck, (if it's only money, it's only money)
