possible levels of service:
a) costs what they said, it works, and no collateral damage
b) costs a lot more than they said but it works and no collateral damage c) costs a lot more than they said, there is collateral damage, but it work= s
d) costs a lot more than they said , there is collateral damage, and it doe= sn't work
Robert says (a)
Generally I'm hearing (d) from most people.
I would jump on it even at (b).

Yikees.   What is it going to take?  T= hat level of service is my greatest  fear.
