I'm obsessed with my new baby heartbeat monitor. IMO, its a must-have for any prego. It's absolutely amazing to hear the little "thump thump" of the baby inside my belly. I have it beside my bed so I can listen every night, and every morning when I wake up. The one I got - Summer Infant Heart-to-Heart Prenatal Listening System -- was only $19.99 from Babies R Us. It comes with 2 sets of headphones so my husband can listen at the same time. It works best if you are laying down, with a few pillows behind you. LOVE IT!!
