I have a set of the disconnect tools for the fuel rails and a/c. They work pretty good. I also have the 02 socket. That works good too but if you are not careful with the wire, you can still mess it up. $25 is a bit high though. I bought mine at autozone for about $8.
I've never seen those testing tools for the tfi and computer. New news to me.
