Looking for NOISY Pager

I am looking for a special purpose pager to receive email that will make a
lot of noise for say one minute. I have specific notification emails I
will occasionally get that need to wake me from sleep if I get them. I
sleep right through my regular pager. It's equally important that the
pager stop its alarms after some finite time period, because there will be
times when I don't have the pager with me and I don't want to annoy others
at home with it. Are there any good candidates for this?
