Where can I buy a whizzball or Zip ball, not sure of its name?

[figleaf]

You know the sort of thing... one person holds the handles at one end and opens their arms and the ball shoots to the other end then that parson opens their arms and the ball shoots back?

Do they still exsist or am I mad.

Thanks for that Hausfrau I will ring ELC if I get no joy elsewhere. Anyone know of where I can get one now. DS has an exercise prog to complete and the Oc.Therapy lady says one of theses would be perfect for part of it.
