i've had the gameboy end of a gba sp charger cable coming out of my pc for a fair while now.. after i couldnt find a male usb plug..
stepdown converters are pretty cheap off lik-sang i think.. most of them dont come with an australian plug, but thats an easy fix.. oh, and if you have something like a 240v ps2 and a 110v one, dont keep them next to each other.. the mistake will happen eventually.. i know from experience.. you think youll check every time, untill you forget. then you get to know what a ps2 in pain smells like. thankfully mine worked again after i got a new psu. now i have a 240v japanese ps2.. lol, the shop only had australian psu's.
one good thing about australia, is almost every new tv you buy will be dual format, and will run both pal and ntsc.
anyway, lawrence, where you moving to? if its not the east coast, youre gonna get bored eventually.. im in adelaide, and theres NOTHING to do here, though you could be into completely different stuff.. i dunno
also we have piles of living things that can kill you:D though you've probably heard.
do you like 2-4 inch spiders? cos youll get those on the walls in your house:) but dont worry, those are harmless, leave them alone, and theyll leave you alone.
i love telling people all the nasty things thell find here, theres a fair bit of it too:P
overall its a good place to live, better in the eastern cities though.
btw. you can buy cigarette lighter transformers which have a switch on them to select various voltages, and one of those ends with like 5 diff plugs, so they fit most things. i have one which has gameboy (classic), gamegear, and lynx mentioned on the box, plus has a few other standard connectors. my car gets up to 14-16V, depending on if im accelerating or not, so it wouldnt be wise to plug it straight in..
