That is some of the best advice I have seen on an email list, and I am on
a bunch of them.
Generally I will 2nd that, or 3rd it as the case may be. It simply cannot
be emphasized enough. I am a retired (I'll be 80 on 2 months) broadcast
engineer who got his diploma from the School of Hard Knocks. And I am
still getting my hands dirty, they do fit the tools.
