I am going to be getting a wii in about 1 week. I have done a ton of reading about all the things i need to do and have came to a conclusion i want to try as hard as possible to get a wii that i will be able to install bootmii into the boot2. I like the idea of me really not being able to mess the thing up after i make a nand back up. I am picking up a used wii and have about 12 options as far as serial numbers go. (Yes i work at a gamestop so i can check). The only definate thing i have read is that you better stay away from Lu65+ and that it seems anything starting with a 1 is a go otherwise you could have a lu35 system you can not bootmii on. If you can't tell i am looking for a US system. Any other numbers that are generally safe to buy?
