Thanks for the replies, sorry I haven't been able to get back to you all sooner!
Mike, I'm sure Frizza's swimming in them, if we get desperate enough to be paying postage etc, I might get in touch with him.
Reid, I have no idea mate, who know's WHAT kids get up to when you're not around?!
Molli, that sounds absolutely perfect, I would love to relieve you of your, err, 'collection'. Although I pass by the city regularly, getting into the actual CBD is usually pretty tricky (time wise), unless I make a special trip up and catch up with friends at the same time. I'll PM you and see if we can work something out.
