https://www.amazon.com/dp/B078PDH6Z8?th=1 I'll give a shoutout for this one. Works surprisingly well for how cheap it is. It's helpful for backing up mostly so I can see my wife guiding me in and to give me some sense as to how deep I am into the site/driveway. I find it probably more valuable when driving though being able to see what is coming up behind me, especially I need to change lanes in traffic or in town.
