General rule, if its less than $80 its probably a clone with upscaling or less a chipset/guts.
Theres a dashcam thread about somewhere, that has samples of the many I've had. (DVR-027, Mini0805, G1W-CB).
They all come with relatively long cables, so for mine I've run them across the passenger visor down behind the trim into the ciggy port area. Watch your memory cards, largest bringer of issues. You would think a Class10 samsung from 1-day would be the knees. Nope, I've had 2 fail with constant writes. Transcend seems to truck on.
