Tools for differential rebuild

I want to start buying the tools I will need for rebuilding/ re-gearing my differentials, I have a FMS that tell me all the special tools that I will need and I know that I can buy them from millerspecialstools.com. The only problem is that they are so expensive. I haven't asked matco or snap-on dealers in my area. Does any body know where I can buy these tools for a bit cheaper.

Thanks.
