just for info
got a US wii, (using it in UK) modded with D2pro v1.1b (at present)
you can use a UK wii power supply on it, works a treat, so no need for a step down
as mine is modded, it is region free, so i use brickblocker on PAL games which work well.
i connected it to the net here in the UK and it connected to the US servers and downloaded latest wii firmware.
mario kart, SSBB and mario galaxy work a treat
hope this helps
