I am really, really pissed off with my PS2

I think that you are basically screwed if you opened your PS2, thus removing the warranty sticker. If that sticker is removed, then they will just tell you that you were the one who damaged it probably.

And Jonbo, I think you are incorrect about your last statement. Sony did indeed upgrade the PS2's that they are making. I am not sure if they are more "stable", but they did receive an upgrade nonetheless.
