A quick search on Amazon shows that you can get "low end" chastity devices for both men and women around that price point (I am not sure whether I look forward to seeing the ads that will now follow me around the web for the next few days, but who knows what I'll learn)

EDIT: Startup idea: Fetish toy in the form of a chastity device that gives the wearer an electric shock if they try to access blocked sites. I love the thought of "abusing" such a filter to power a BDSM toy that the supporters of the bill will surely find obscene.
