People say this because of the style of the initial posts. The nature
of the problem is that it is scary to use as a learning experience.
Learning experiences are best carried out on those little Radio Shack
type electronic kits. I had the good fortune to work alongside a
really experienced pro one day when we had a job that we couldn't
handle. The interesting thing about him is that although he was
very experienced, he worked slowly and spend over half the time
checking things and taking care of safety issues. The job was done
exactly on time, as he said it would be. I asked him why he was so
safe, and he told me that his dad, doing the same kind of work for a
living, messed up on a job and died. His dad was also very
experienced, but a bit more careless.

There are some pro-electrician www sites. I can't remember the names
offhand, but they may be found via www searches. You can get some very
good code annotated books at Borders and Barnes and Noble in the
engineering section. There are also a lot of books at the library.
The discussions that you will be interested in are between pro's
discussing botched jobs, redone jobs, code violations, etc.
: What is the technical name for a "fox and hound"?
Inductive line tracer? Just ask for fox and hound at a good electronics
store (not Radio Shack). There is a design on the web for one, but
since I didn't want to mess around, I just bought one. They cost about
$70. You can buy a dedicated one for about $300 which has longer range
and can be used with live wires. You can also design one, since the
limitation in the lower cost model is the blocking capacitor and
transmitter. Decrease the value of the capacitor, or put a lower value
in series, and replace the transmitter. Or better yet, buy one. Or
better yet, hire a professional electrician :-)
