I think that if you don't work at a motherboard factory, you can better
invest the price of a rework bench in a good logic analyzer. If you end
up having to replace that one BGA IC, you can scrap the board. Any of
the other hundreds of components can be removed with a tube of
chip-quik and a $5 soldering iron from radio shack.

You would have to replace an awful lot of bridge chips to make up the
cost of a BGA rework station.
