Good job Todd,
My trackpas is over too and I intend to repair it by myself.
I have a macbook pro 13" mid 2009.
I've heard that trackpad price in the apple store was around 75 dollars and it is pretty much the same price you can find on ebay or other shops.
Anyway, the only question I have is about the tools you need to repair : some people say that the tri-wing screw is for removing the battery and others to remove the trackpad itself. Are the screws of the trackpad normal one or tri-wings too ???
Thanks
