I think Angelcare is introducing a new monitor, with the room temperature and digital display in it - Its going to be a bit more expensive $329 (if my memory serves me correctly), compared to the one that is out at the moment (same two pads, but no room temperature or digital display) which is about $200.... or so the lady at the baby shop, just before xmas told us. We are going for the standard one (two pads et al).. if our tight budget stretches that far!
This came out in June 2 pads, digital display with room moniter and 2 handsets as I have it its great
