I see quite a few votes for Sigmas, most on the longer and or wider end, but i am glad to see i still have the choice between Tamron and Sigma, (loved my 24-70/2.8 and 10-20 on the 30D)
I guess if i get the Sigma 18-50 or the Pentax 16-50 will largely depend on how my sale of old lenses and adapters goes on "FM.com"'s B&S forum.
Tarsus: i am glad i can adjust AF on the K20D, and test if i can adjust my lens to hit focus well on f/2.8 or do you mean you tried to shoot things at an angle and the best yet soft spot was exactly on what you had focused on? In that case i'd take it back, shouldn't be worse than the kit lens
