I see very little discussion of high end immersion blenders other than Bamix and Waring. I think that people may be missing out on some other great options for higher quality (possibly longer lasting) mixers. I purchased an immersion blender for my wife this Christmas and did some internet searching for recommendations by users of the home oriented mixers (sounds like Bamix and some of the Waring mixers could be used at home or commercially) and also looked at restaurant/chef supply businesses. I considered Waring, Cuisinart, KitchenAid, Bamix, Hamilton Beach, etc and from the restaurant/chef supply businesses Dynamic and Robot Coupe. Dynamic and Robot Coupe manufacture a wide range of immersion blenders with prices from $139 to over $1000. Due to size of the mixer and cost, most of these would only be used in commercial settings where durability for frequent use and ability to mix large quantities are required. However Dynamic and Robot Coupe make some smaller immersion mixers that would compare in size, cost, and weight to the Bamix units. Dynamic has a MiniPro ($139 with free shipping on eBay currently, supposedly lists for over $300) that is 120-200 Watts (variable speed using a dial at the top, watts increase as you dial up the speed) and a 7" shaft of very stout stainless steel. It comes with 4 different blades, two being titanium coated for added wear durability. Robot Coupe also has a 7" shaft unit that compares to the MiniPro but at a higher cost (somewhere under $250 I believe). I bought the Dynamic MiniPro for my wife and having used it and looked it over carefully, it is a very high quality mixer. My thoughts in buying the Dynamic mixer were to get high quality (thinking that a company that makes large $1000+ commercially proven units probably make a good smaller one also) and the $139 I paid compares very well to what the Bamix and Waring mixers cost. Only time will tell if I made a good decision but I think I did. I encourage others to consider Dynamic and Robot Coupe.
