You can usually find those lights pretty cheap at any place that sells old
office junk.

Checked the price of old office junk recently? I almost choked over a file
cabinet price the other day, and left without buying an office chair. Almost
cheaper to go new these days.

Not to mention you'd likely have to replace the battery in a used one.

http://www.grainger.com/ (search for emergency light) has a number of
them available in the USD50 range.
