We have the Tommee Tippee Sensor one - very similar to the angelcare one. I know Baby Bunting have on sale until the end of this weekend for $159 of if you wait until target have a baby sale they are usually about $150

The Tommee Tippee one is great, it has a green light on the monitor and parents unit that flashes so you know bubs is breathing and the alarm goes off in 20 seconds if no movement detected. Also, you can activate it so you can actually hear a 'tic' with each breath if you want too. It also has a night light and room temperature

Its super sensitive too, we can also hear bubs fart - LOL

I would definately recommend this one too
