What wattage do I need in an immersion blender?

Higher advertised wattage (many budget units claim 1000W+) does not always translate to better blending, and reviewers caution that motor claims on lower-cost models are inconsistent. For most home cooks making soups, smoothies and sauces, a well-built 350-625W unit like the Braun MultiQuick or Vitamix handles everyday tasks comfortably.
