We ended up not really using a monitor with DS.
We haven't gotten any because she is just going to be in the room with us. Even after being out of the bassinet. I tend to keep my babies in the room with me for a long while, lol. I have been thinking about getting one now though that we have a 2 story house, incase I come down stairs and she is still asleep. I dunno though, and it has been so long I don't even know where to start with monitors.
