Product review (5 stars): Installation isn't THAT bad, but not for the faint of heart.
The gasket is pretty straightforward.  Thankfully I didn't have to deal with the steam feature, etc so I didn't have to cut any holes.

The ring snap pliers tool is a near MUST-HAVE if you're not mechanically inclined.  I am, and using repeated applications of dish soap, elbow grease, and believe it or not plastic serving spoons and spatulas, I was able to properly re-install the outer spring, which took the better part of an hour and probably 20 tries.  However, well worth it, and well worth not paying the certain hundreds of dollars on a professional repair.
