If you're ready to upgrade to a real blender, I can tell you from experience that it's the worth the investment. I recently moved up from whatever cheap thing was collecting dust in my parents' basement to a souped-up version -- and found that I used it far more frequently. The good news there is, aside from the occasional batch of frozen drinks, most of what comes out of a blender is usually pretty healthy: shakes, smoothies, soups and the like. Speaking of blender investment, you don't have to empty your savings to get an elite model such as the powerfulwhich is right now at Macy's. That's $90 of the normal price and $40 cheaper than we found it at or anywhere else.
The beauty of this particular blender system is how much you can do with it. It's got the large 72-ounce blending container and two 16-ounce blender cups to make smoothies and shakes and take them on the go. There's also a 64-ounce round bowl that functions as a food processor so you're really getting a high-octane food chopper in addition to a very powerful 1500-watt blender.
I've personally tested many a Ninja blender including this one and have found them to be the best blenders at this second price tier, right under Vitamix, Breville and Blendtec -- all of which will run you $250 or more. Macy's will ship the Mega Kitchen System for free or you can pick it up later today at your local branch, pending inventory.
