DS10 has asked for a stunt scooter for Christmas to replace his 'babyish' one and I haven't got a clue where to start and when I asked him he said one where the wheels don't make a loud bang when you jump on it!! Help!! Looking to spend about £70 but don't know if that's a reasonable amount. Should also mention he has aspergers and is desperate to fit in with the right brand. I know it shouldn't matter but he is totally fixated on it at the moment.
