$199 for a dashcam is a bit ridiculous in my opinion. There are cheaper options out there, such as the dashcam from Xiaomi at $129 (or sometimes $99 if it's on special). But even then, I wouldn't spend $100 on a dashcam. I used to use one, but I don't anymore. At my street, our cars get broken into a lot and it doesn't help that our street is full of exotic or fancy cars, which unfortunately attract those lowlifes. If you have anything like a GPS or dashcam in your car, they'll break in and take them. Then you end up spending at least $200 on window repair and have to deal with all this mess.
My recommendation is to use a dashcam app on your phone. Mosf ot them are free, offer many features and best of all, it uses the already good camera on your phone to record those footage.
On Android, I use Autoboy. It can upload the video to Youtube for you automatically, so that you'll always have a backup. It has cyclic recording and so it'll never use more than the max amount of storage space that you define. It offers other features as well and it's free. Just use your phone for GPS, dashcam, etc.
