BDChopper,
Re. the possible choice of Scout, my question would be 'Why?'
With due respect to the ex-mil guys who are operating these on the civilian register, I don't think it's a sensible choice for PPL flying.
For equal 'ex-mil' appeal, the Bell 47 Sioux will give you as much fun, cheaper per hour and much, much safer to EOL.
If not a piston, then how about an Allouette? But, there's no such thing as a cheap turbine, especially if its ex-military. This would be my choice above the Scout or Gazelle.
