@Lurch:
I'm in New Zealand as well (Christchurch) and have a bit of spare stuff, though no decent accelerator boards, and not much A1200 stuff. Give me a yell if you need any commonish bits...
Have you contacted Jeff Kavelaars in Auckland? I recently read of someone in the country selling some semi-decent A1200 bits but I forget the details.
I have a spare A1200 with Viper 030, but I'll gather you'll want something with a bit more go.
