My friend has a Ninja blender. It looks like one of those rare as seen on TV things that may work. It seems to work great but is expensive. Have you found other appliances that are worth it from the TV? I like to buy things in person (after looking at Amazon reviews) or get them on Amazon, but personal reviews seem just as important, if not more so. My friend's Ninja made pesto... I'd like to make sauces, smoothies, fresh whipping cream, and puree soups. Are there good blenders for that besides the Ninja?
