I recently attended a thermomix party my friend was having. It was a great demonstration and the food was quick and easy to prepare, and I have been thinking about it ever since. however it is a huge investment. It costs just over $2,000. Does anyone have one and if so is it so much better than a blender and hand whisk (I know it stirs your food etc too) but would you say it was worth the investment or is it shoved in a corner and used once a year?
