looking for lens for Nikon D-60 camera- Home Staging purposes

Hello!  I'm looking for the best price to a lens for my camera, but don't want to pay $700 for it.  Has anyone seen this lens for less--new or used?

Nikon 10.5 mm DX f/2.8 G IF-ED AF Lens

I also read this: 

If you take a shot and want to reduce the barrel distortion, you can apply a filter such as the Image Trends Hemi to "straighten" most of the distortion, but still keep the 180 degree view.

so I will also be looking for this filter.  Please let me know if stumble across either of these items if you're looking on web or in sale literature.  Any help is appreciated.

Thanks,

Cathy
