I looked at the one on the Amazon link. That's not something to have in the apartment, though!

It says: "Recommended not to be used within 25-feet of area intended for human activity, should not be attached to house or deck or other structures"

I just did some Google exploring. Looks like Sears (at the mall a couple miles from me!) has a good tennis-racket one that just might do the trick! I must check that out tomorrow.

Thanks for the suggestion, Vette!
