SIDS/breathing monitors!

What brand/model will you be using? We used angelcare with my daughter but I know a lot of new things have come out the past three years.
Originally I wasn't going to get one because the one with my daughter kept going off in the middle of the night for no reason and would scare the hell out of me and my anxiety would be through the roof every night.
Talking to my mom though she convinced me to get one because I had totally forgot my cousins daughter had breathing issues and a monitor was a godsend MANY times when she was an infant and I suppose I was just letting fear get in my way. What are good models/brands? What are you using? We don't have a ton of money it want good quality without breaking out bank acct! Thanks in advance!
