Product review (5 stars): Solved the problem easily
The original ice maker stopped working.  I wasn't totally sure what the problem was but didn't want to spend $200+ for the GE repairman. I removed the old ice maker which was very easy - loosen 2 screws and unplug the electical.

After doing some research I saw I could order the replacement GE part for $130 or so on the web.  This compatible part was $50.  I decided to give it a try since I wasn't sure the ice maker itself was the problem.  It seemed well constructed and was packaged well. It fit the location in the freezer perfectly and started to work right away.  Ice making was back in business.  We have had no issues with it since installed.  It turns out the old ice maker must have just died and we needed a new one.  So far this seems to fit the bill 100%.  We won't know for sure whether this was a good deal until we see how long it lasts, but so far it looks like a winner.
