I am in the market for a new immersion blender, and I have narrowed down my search to the following: 1) Waring WSB33 – 100 watt, 7” (available for $50+shipping from Webstaurant.com) 2) Waring WSB40 – 350 watt, 10” (available for $124 + shipping from Webstaurant.com) 3) Bamix Delux – 150 watt, ?” (available for $129.95 from Williams-Sonoma) I like the first option because of the price, but I am worried that 100 watts might not have much power. It seems like the cheap models on Amazon have more power than that. However, it is supposed to be a commercial line used in restaurants. Has anyone used this model? If I am going to jump to the next price bracket, it is between the Waring WSB40 or the 150 watt Bamix. I like the Waring because of the power, but I have heard so many good things about the Bamix. It is a Swiss line and the company offers a ten-year warranty. In addition, the Bamix comes with three different blades and an optional mini food processor for an extra $25. I am wondering if those extras make up for the lack of power compared to the Waring WSB40. Any thoughts on any of these models and how they compare?
