Product review (4 stars): Good cheap replacement
While this is not as high of a quality as the expensive replacement ice makers, I wasn't expecting it.  This is a suitable cheap drop in replacement.  It features a plastic coated ice cube tray, tray warming element and a universal fit.  You will probably need to do some very minor adjustments to make it fit, but nothing that would take even the most bumbling handyman 2-3 minutes to do.  This does come with the third screw bracket, but no wiring harness.  Just swap the harness off your old ice maker.

If this ice makes lasts a couple of years, it will be a good investment.  It has worked flawlessly for several months now.

On a side note, if you want to reduce the time the first ice cycle takes, just throw an ice pack on top of the the thing.  There is a thermocouple that feeds back the temperature of the ice tray to the controller.  If it is not reading below freezing, the controller will just wait.  Cooling the whole thing off with ice packs gets the system down to operating temperature within two hours.
