Amanda is the newer model much different to your original kindle. I know the model which I have had since last Dec is a little different to that of a friend who had purchased 12mths previously.
I'm thinking about the food vac and have been looking into the Sunbeam Foodsaver, and waiting to hear more feedback from those who bought the other brand. The drawback about the Sunbeam is the cost of the bags. Then I have to think about whether I am REALLY going to use this often (you girls are a very bad influence)
