Dropped the camera. 18-55mm lens itself didn't break, but the autofocus no longer works.

1. I'm assuming cost of repair is probably not worth it?

2. REPLACEMENT = I don't tend to use a big lens, but want a stock lens that can do the up close work, but with little more zoom than the 55mm.
I'm not a $1000/lens person. I'm kind of hoping for $200-$400 but will pay more if that's what's really needed. Open to Tamron or Sigma lenses.

I photograph people, landscape, portraits, little stuff (almost macro)... and I travel a lot so love something that doesn't take too much room. Photography is only one of many interests so I'm no expert and don't buy the best of everything - but still try to capture those things that intrigue me as thoughtfully & creatively as I can. Amazing images were produced on pinhole cameras, but... lenses do make a difference, I know.

Would appreciate suggestions on appropriate lenses.
