Need some advice (Road Trip)

I have a cross country road trip coming up, and I wanted to pick up a pair of Walkie-Talkies for easy communication while driving in the car (have 3 cars driving together). Is there a particular model you all would recommend? I don’t want anything super cheap, but not super expensive either. Limit right now is around $100.00 for the pair. Any recommendations would be greatly appreciated. Complete Noob here!
