thanks to everyone who has already helped me out on the forums. i hope to return the words of wisdom. so far i've replaced a water pressure regulator in my house that corroded, built a home theatre with in-wall speakers and replaced a toilet down to installing a new flange. current items on the list are: running 100A to a sub-panel in the garage, fixing leaking shower knobs in a 1930's tub. both items have threads already going.
