Every doctor I've spoken too dosent recommend to get one for home, they said it creates a false sense of secutiry later in the pregnancy if bubs movements have slowed or stopped and you are relying on the heartbeat, the baby can still be in trouble and the heartbeat dosent show it for a long time. People have lost babys apparently relying on it so no matter how anxious I've been with mine, I've always gone with movement.

It is lovley hearing the heard beat the first time at the dating scan however
