Baby monitor help!

We bought the nanit with wall mount which is extremely expensive and now apparently you can’t take it with you anywhere because for that we had to buy the one with the floor stand which is 100 dollars more. Since I bought it way long ago and can’t return it I’m looking to buy a monitor that isn’t as pricey and I can transport with me. can anyone recommend a good quality monitor that isn’t so pricey and also should I buy one with WiFi that connects to my phone or should I just go with the traditional video monitors?
