I'm on my 3rd hand blender in 23 yrs- Braun with 3 heads- not expensive.

What I would look out for however is that it's going to be easy to clean INSIDE the head ( where the blades are)
I bought one recently in France ( see...can't cope without one there either!!)
and I didn't check inside the 'cup' bit first.
It's a right bu@@er to clean- just can't get the washing up brush inside to get the liquid/paste out...and that must be a salmonella attack waiting to happen
Almost feel like giving it to charity, (but they won't take electrical goods!)..but I'm not quite that spoilt (yet!)!

Ps- I use mine mainly for soups and pastes and taking the lumps out of my custard and gravy!!
