I'm a tech here, but I got a free fridge off of Craig's List. It wasn't cooling well. I put in an after-market cold control/thermostat, and then had to adjust the temp really high (normal is half, but that froze stuff).
Anyway, I moved it into my house and dumped the old fridge with the broken shelves, and have a new(ish) sxs that was a great deal!
I spent $34.99.
If any dyi folks read this; you don't have to be a tech to do this. Just get a truck and pick up cosmetically good machines from Craig's list free. You can post here on how to repair it, and the techs will walk you through it.
Imagine a world of free appliances. All you need is to show a bit of motivation....
