Reddit mentions of Dashboard Camera, SplashETech Mini 0806 Dash CamWorld's Smallest Dash Camera W/ Screen Amba A7LA50 + OV4689, HDR, Full HD 1296P, Car Recorder, Dvr Car Camera with GPS Logger

I would like to amend my last post and say something $80-$150 is good quality.

I bought this one:
https://www.amazon.com/gp/product/B00XKM5A96/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I'll note that it was $129.99 when I bought it and I got the hardwire kit for it. I wired it into my cigarette lighter in the front and ran the wire all the way around the car up to the mirror.

It works great, but it is now randomly turning itself off. I know it comes on when I start the car, but after about 5 minutes it shuts off. I have to reach forward and power it on manually, but then it's fine until I turn the car off again.

I am also having problems with it not overwriting itself properly. These things are supposed to record until the SD card is full, then go back to the earliest recording and record over it, five minute blocks at a time. But occasionally, when the SD card gets full, it beeps like crazy saying memory error. I have to remove it from the cradle, and re connect it. Mildly annoying.

I like that it has great image quality, and can save onto two SD cards at a time, up to 128GB each. Overall I don't hate it, but I wish I had sprung for something of much higher quality.

www.reddit.com/r/dashcam is a good resource for what to buy. check their sidebar.

Mystery budget: aukey looks to have a 0803 rebadge for $60 worth a look

Discrete: Street guardian has this model that is hard to find but allows you to mount on dash and have a remote control mounted elsewhere.
