Anyone have any recommendations for one of the battery boost/jump start devices? My standard transmission Tacoma will start easily by rolling off a slight incline, but I do not always think to park in such a place. I can't recall ever having a dead battery out in the hills, but having the backup seems prudent.... I do not need the accessory compressor or light that comes on some models. Prices seem to range from inexpensive to exorbitant!
