I managed to find it. I was waiting for my wife to come home, but I found it, this site you just can't miss :) http://www.heartbeatsathome.com/ http://www.heartbeatsathome.com/ This is what we used and it is more than enough and you can carry it with yourself. Their customer service is also really nice, but you will not need it. Buy extra gel for doppler and you will fine.
