Dash cameras: good idea or paranoia

[PDenbigh]

soooo....the 12v plug charger stopped working. so i decided to hardwire it, since I wanted to do that anyway.
*pop* *burning smell*
did not occur to me that it took 5v NOT 12v and could not be hardwired without a 12v to 5v step down converter.

$100 mistake, back to square one.

How much would you sell the old one for? Not saying I can fix it, but it'd be interesting to try.
