They're an offshoot of Radio Shack/Tandy. The local one is at 1550 S.
Colorado - in the block just north of Computer City. They keep running
the pointers on special at $9.95 (regularly $19.95) and, according to
their Yellow Pages ad, they do have a website. www.techam.com

On another matter, has anyone with dual projectors with zoom lenses done
a little test to determine what the human tolerance is for focal length
mismatch? What are the odds of a person's eyes exactly matching in focal
length?
