Hi DS (5) has outgrown his mini-micro scooter, (plus we left it somewhere, I've no idea where). Anyway he needs a new one. Wants a 2 wheel one. I'm thinking we don't need to spend £80 or whatever the micro equivalent of the 3 wheeler costs, but I would like something that's not going to break in 2 months. Maybe spending upto £40 if necessary. Any ideas what should get?
