Had to bump up to $270 under pressure, but I'm still happy.
BTW, can you guys explain exactly what you mean by filing down the charger?
The two sharp teeth on the bottom side of the USB. They snag the inside of the port to prevent from slipping out, but time after time of yanking the charger out with those teeth hooking the inside is what usually breaks the USB. Or you could try reinforcing the female USB with epoxy.
