I didn't realise that A4000 was in Sydney until you just said that. Unfortunately, I won't be bidding; I just bought an A2000 which cleaned me out of 'Amiga money' for now :lol:
If you were interested in buying it, you could always ask for the seller to have it couriered down, it would be safer than post, and shouldn't cost more than $30, I'd say. I'd be able to help with transfer, but I'm not coming down to Melbourne any time soon, too much rain for my liking :lol:
