Baby monitor

Samantha • I am me.
So my bf and I are moving into a two bedroom condo and this will be the first time my son will have his own and won't be sleeping in our room with us so I'm looking into baby monitors but here's my dilemma. As much as i would love to get a fancy baby video monitor I can't afford one obviously we don't have a lot of money at the moment since we are moving and had to pay a lot to do get everything taken care of so I'm not looking to spend anymore then $20-$40 so I was wanting any suggestions from any of you ladies. What's a good reliable brand?
