Hi,
sorry to hijack this thread but i'm basically asking the same question. I've done a bit of rooting around on the net and found out my U.S Wii starts witht he serial number LU511 which apparently means its D2A/DMS/D2B without cut pins
then trying to decipher what this means it looks like i can have a wiikey or cyclowiz chip fitted. I've just read the pros and cons and apart from the stealth option they seem identical (to my eye anyway). So i'm most probably answering my own question but should i go for the Wiikey as the cyclowiz seems out of stock in a few places or wait.
cheers
