Hello, and welcome to my first post. After doing several softmods on friends' Wiis I've finally caved and decided I need to get one myself (I know, late, right?) I've done all the research I need to get into softmodding, and now I'm looking for a Wii with a hackable boot2. Is there any advice as to what to look for as far as serial numbers go, etc to have the best luck getting one off ebay/cl? Also I was reading here a bit, should I upgrade to 4.0 regardless of the current FW version, or only if the FW is > a certain revision?
