Are you looking for Allen Bradley products or just siemens?If you are in America, you would be best off with Allen Brad. plus you need the RSlinx and RSlogix software to connect and write programs using ladder logic. If you are European, you need a Siemens product of which I am not as familiar with. They all use the same principle though. I would try EBAY first off and then look into some Vocational schools that teach PLC programming to see if they have some older PLCs that they may donate or sell. Good luck!
