Another side of that idea is that you often don't need the more expensive features. My immersion blender is the cheapest thing I could get my grubby little mitts on. It reaches to the bottom of the deepest pot I care to use it with, it's plenty powerful to chop up veggies smoothly, and it doesn't overheat on sustained use. It would not work in a professional kitchen, but I don't run a professional kitchen. Any additional expenditure would have been wasted, and if the item were bigger, were heavier, or had more attachments, those would just represent a waste of space in my house.
