I did exactly this for my drinks fridge, I think it was like 800 for a 3-3.5k stainless fridge because of a decent scratch/indent in the front. no fuckeths giveths.
your going ot have a hard time finding a used fridge for around $80, when comed gives you a $75 credit on your account for picking up a working one, and the pickup is free. **its eitehr $75 or $50.
