I have a Xbox that I haven't played in a while and I want to mod it so that I can play some burned games. I noticed that there are some very cheap modchips ($10-$20) and some very expensive ones($50-$90). Can anyone recommend me a mod chip to buy? I want it to be easy to install as I only have some soldering experience from high school engineering class. I heard solderless solutions are not reliable, is this true?
