Where can I find a cheap broken frrzer for grow box!

I have been searching craigslist for appliances trying to find a PoS deep freezer to buy, but I was wondering if there were places that had junk (preferably not working) deep freezers so i can make a mother/clone box!!! Any suggestions would help, my spending limit is $50 (Yes craigslist has a few like that, its just hard being the first caller!)

Also ANYTHING that is selaed like that, that anyone can think of and suggest would work, just looking to keep one at the MOST two mothers.

Thanks,

Bargar
