should i buy a speedotron 2401a? found one with 2 heads on cl for $100, but its in a bit rough shape. one of the heads needs a new bulb and it will need a new power cord for the pack. called the guy, he used to be a stagehand and this one was used for several model shoots for hallmark and worked fine when he put it into his garage a couple years ago. so, think its a good buy? would i need to plan on replacing the battery in the pack before i could really use it? would it be worth even buying to flip?
