Where can I get accessories and power adapter for Powerbook

My father just bought me second hand a Powerbook 180c. It looks to be in great condition. But it can't be checked to make sure as the battery is dead and the power adapter was not with it. I've looked on line at various stores, Office Depot, Staples, Amazon, Buy, etc only to find that they either do not carry Apple products or the accessories and power adapters would not work. Or the prices are disgustingly high. Due to illness I cannot work and my parents are on a limited budget. Does anyone know what sites carry accessories and power adapters that will work on the 180c without breaking the bank, atleast a power adapter for now, to see if the 180c even works? Any advice appreciated.
