Okay, I have never posted anything on this forum before, and I never thought I would but I really need some opinions and help on my problems.

1. I bought a Wii from Singapore about two years ago, I bought it because it was the 25th Anniversary Mario Edition (the Red one) and when I asked, they said it could be played in Malaysia (That's where I stay) without any problem.

2. Recently, I bought some PAL games from UK, (I never bought or played any other Wii game that was not included in my console), but after doing some researching, Wikipedia told me that Malaysia and Singapore were under PAL region, so I thought that it would be okay to buy some games there.

3. When I checked my wii to see whether it was PAL region (by looking at the games to see whether it had PAL or not), there was nothing to be found and sure enough, my Wii couldn't read my disc. I don't know if my Wii is from US or Japan, probably US :/

4. At first, I considered modding my wii to play all regions but I still want to update my wii and I don't really want to mess with it that much. I also considered buying a PAL wii since my friend would be going to the UK soon.

5. But then, if my console is a US version, I have been playing it without the use of a step-down transformer for a year! Wouldn't it cause a power surge due to the fact that Malaysia has a higher voltage? I really don't want to burn my house down. I know that there are several cases where it happens

All these problems are nigging at the back of my head. And I really really need help on solvnig this problems.
I really am against modding my Wii at the moment though. But I spent quite an amount of cash on the UK games :/

So my questions are:
1. What should I do with my situation? Buy a new PAL wii? From where?
2. Is it safe to use my Wii? I'm now unsure if I'm jeopardizing my family by playing it now >.<

Sorry about the long post, but I've been holding all this for some time, and I needed help before my heart exploded. I appreciate any feedback regarding my problem
