Product review (5 stars): Whirlpool 2198597 Icemaker
This ice maker was easy to install.  The water chute is a litter taller than the original but actually works better since the fill hose fits down into it further.  It started making ice soon after the installation was complete.  I would recommend this to anyone thinking about replacing their ice maker.  The only thing needed from the old one was the base, which only takes three screws to change.
