im 12 also, (although in 5 days 13), i ask for all my stuff for birthday or christmas, or otherwise I ask for money for birthday/christmas, and buy the parts myself. Also I dont get regular pocket money unless i do somthing (fair enough really) so at least for me, just doing extra random helpful jobs around your house is a good way =D. (I wish some1 took me seriously too, i want a job)
Thanks
Joe
