Thank you members for the answers so far. I think I need to explain further the purpose of the blender I need. First wanted to say that I live in Europe in Portugal and work in a design hotel in the Oporto city. My bar has a list of several cocktails and a section of smoothies and milkshakes that wanted to improve. I would also implement the frozen cocktails that are a current flaw in the menu. So needed a good blender that was not too expensive because not justify having a very expensive for the amount of drinks in question, that i currently serve. Between milkshakes, smoothies and frozen cocktails that i serve no more than 10 daily on average .... So needed a blender with average value that could do the job ....Note: i don´t have available to buy, here in Portugal, the blenders that you mentioned ... the best I could at an affordable price and that can meet the needs are the Kitchenaid Artisan ($ 300) and Rio Hamilton Beach Commercial Blender ($ 380) .... However I think the Kitchenaid is more targeted for kitchen ... dont you think?
