177 US for 3 Matrix chips.
I can only think of one possible problem with this chip and huge noobs:
"Hi, yesterday I Installed the matrix chip, unfortunately i bought a star screwdriver but I only have square screws, since im out of funds because I already bought 3 xboxes (enigmah, Doh!, Messiah, Doh!, X-ecuter, Doh). I amm screwed, is it possible to solder the screw to the chip and punch it in place with a hammer? thanks for your help".
