That all said, if you can justify your use of them in a particular context you should probably just ignore those saying not to use them without the same knowledge of your situation. The reward may be worth the risk/cost but the people yelling out for you to be careful are not doing so for the fun of it. You should at least heed it to the point of saying, "yes, I'm sure I want to do this". David J.
