My battles with the game consoles

My son loves video games as much or more than most kids his age. At the same time though, he has more problems with them than I expect most have. He has had an Xbox360 RROD then it was fixed but now it has random freezes. Then we got another one and his sister decided to pour oatmeal in it. He has 2 old style Xbox consoles as well and I had to solder the power connector back into one and replace the DVD drive in the other. His Nintendo DS Lite had to be shipped in for warranty work at the start of the year. Finally, his Nintendo Wii had the power cord become separated at the tip last week so I replaced it and last night his sensor bar quit working and I replaced it as well.
   As fun as they are these systems don't seem worth the money sometimes. He's not hard on them that I am aware of. Do any of you have this many problems?
