Anyone know if you can still buy these? My son was given the command centre for his birthday by someone who didn't realise that no figures came with it... I've been looking out for a while but haven't seen any - should have looked for them when I was in NY recently but was scared to go into ToysRus in case I bought too much (it's sooo cheap there at the moment). If I can't get any more bits for this I'm tempted to give the command centre away to the school Christmas fair.
