Philip,

    What do you think of TDS 1000? Any good things
about it? It will be the biggest investment I would
have for my electronic hobby. Yes, a GOOD DMM is
important. I have used analog and digital. I own Fluke
175. I dare say I wouldn't be able to get any projects
done without it. Simply accurate and fast with it's
readings. =


    I am very tempted in getting FLuke 187! What is
your feedback?

John
