I sent this message to Rowe today.  I wonder if they have an answer?

I have two bc-200, a bc-1400 and two extra bill acceptors. I have had someone smash in two of my bill acceptors. Is there anything I can do to prevent this from happening again? The only advice I have gotten is to get rid of your changers. Is this the best advice? I have some pictures: http://cwguy.com/index.php?s=e03
