F. A. S. T. system, has anyone used them?

I'm currently in the process of figuring everything out, I went through Richard @ FASTMAN EFI to purchase everything instead of CompCams(owner of F.A.S.T) He has helped me with everything and once I get it started will help me dial it in via the interwebs and custom programs he will sent me on CD's, I went with XFI.
