It's still AF, and I think mine actually focused faster non-SDM than it does now that I've and it repaired. And that's on a K5 - k3 has a faster AF motor, so presumably it'd be better still, there. Louder, of course, but it's not like it's *loud* -- just not silent.
The repair issues might partially be because Pentax has apparently changed their preferred repair partner in the US? I don't know details on that, just saw it mentioned in a few posts. I had mine done at CRIS, and anytime I updated the repair ticket, they usually responded within a day to tell me yet again that they had no idea when Pentax would send them the pats they needed.
They only charged me an extra ... I think like $120 for the SDM repair since they had the lens open and in pieces to repair the other damage anyway.
