I am thinking about getting one of these - does anyone have one who can report on how well it works? I have a Zojirushi fuzzy logic rice cooker at home that is excellent but was thinking about getting a rice cooker for our lake cabin and don't want to spend that much money on a SECOND rice cooker - but it would be nice not to carry the rice cooker back and forth. The Costco one is around $30 - so inexpensive I'm wondering about how well it performs.
