hermetic compressor scrap

I'm looking for a good place to find scrap hermetic compressors. Usually friends give me refridgerators and dehumidifiers now and then but its not enough. I love sutting these things open and getting the copper, its too easy. Where is a good place to find crap refridgerators besides craigslist. Like when sears takes away your old appliance, where do they take it? Can I get them from there? Preferably where I could get them with the lines already cut, I don't care what they did with the freon, but them knowing that I will be cutting them may lead to issues. Any ideas.
