The ebay tool that I got is like a pair of pliers that fit the seals perfectly. They have teeth and a lip on the bottom for removing the seals. The Toyota part I have seen has 3 or 4 jaws that you lower down on the seal for removal. I can't locate any pictures though.
I made one using 3/4" PVC and a magnetic pickup tool. I made the magnetic pickuptool fit snug in the end of the pipe. There is alot of info on making this tool in the diy valve stem replacement thread. I have used this tool twice and it works great.
