Minifigs.me who you will have seen both here & in the media, do some amazing personalised lego figures, in fact it's what they do best!
If you visit their site you could have a lego replica of your Cub or Beaver (right down to the colour of neckerchief) complete with various distinguishing characteristics that make your child unique!
Ok not cheap but a lot of work go's into them & infinitely more durable than "yet another" easter egg ..for example!
The neckerchief can be customised to a group’s colours. The listing is for the default head and hair shown. If you add alternative heads/hair they will REPLACE these ones. You can see their head and hair selection here.
