Nikkor lens problem (manual focus is stuck)?

I have a 18-55 F3.5-5.6G Ed II AF-S DX Nikkor Zoom Lens, and a few months back it fell off a table and landed right on the edge of the lens. (luckily I had a UV filter on it so it just chipped the edge of it). Recently the manual zoom is stuck. The auto-zoom works just fine but when I switch it over to the manual focus nothing happens. It is acting like it is not switching over. Can this be fixed? Or do I need to send it in for repairs? I probably won't send it in because it is not the best of lenses and I hardly use it. Probably costs the same to repair it than getting a new one.

Added (1). "Auto focus" not auto zoom.

There's no "auto-zoom" on this or any other DSLR lens. Did you mean the auto-focus? If you can't turn the focus ring, when the lens switch is set to M, then it's either a problem with the switch or the actual focus ring has been dented from the impact.

It can be fixed, but it's not a warranty job, since the problem was not from bad design or manufacturer, but from an accident.

I'd just keep using in on AF, as long as it works well. You can find plenty of used ones on Craigslist or Ebay, fairly inexpensively. If not, then it's a good opportunity for an upgrade.

It seems that more than just the UV filter was damaged.

It can be repaired and Nikon can do the repair. If you have an other lens that has the same focal lengths in it like a 18-200 mm, recycle the lens. If not, have it repaired unless you don't shoot landscapes or group shots.

You can get a refurbished 18-55 at the Nikon outlet store fro $159.

But I have seen them used at http://www.adorama.com/...dorama.com and http://www.bhphotovideo.com/...ovideo.com for less.

In either case, your repair bill will probably be at least that much.
