Do you think you actually need a sound and movement monitor? I don't want to be cheap and regret it but I just wonder if it is one of those extras that you don't really need.[/QUOTE]

I guess some people would probably think its a waste of money, but personally I think its great, esp the movement sensor. I sleep a lot easier at night knowing that the alarm will sound if for whatever reason she stops moving. Chances are, that I will never actually need it (breastfed, non-smoking house, slept on her back etc) but it just gives me peace of mind - I think for the sake of a few hundred dollars, it is definately worth it. Then again, I am a bit paranoid, as my cousins baby died of cotdeath when I was a kid, and I know of a another baby through a friend that it happened to as well

We have the 201 - which was given to us, but if I had to buy one I would get the 401. What I like about the 401 is that it has the temp displayed on the parent unit - I go into the babys room so many times at night to check the temp is ok - am paranoid about cooking her!

Also, the night light would be handy too. Plus the 401 has 6 more channels than the 201, we find that we can sometimes pick up the baby next door, or the neighbours tv.

These are just little things, but they are a bit annoying - I would pay the $100 difference to get the better one in the first place.

 I found the 401 at a good price here http://www.littlehedgehog.co.nz/index.php?main_page=product_info&products_id=73 . Also, you could try TM for a second hand one, we had to get ours fixed (cat knocked it over) and the place that serviced it was great, so I wouldn't be too worried about buying second hand.
