The time you waste going back and forth to your local shop, who
obviously doesn't know how to properly stress relieve and tension a
wheel, will more than make up for one trip to the reputable bike
shop who can probably fix the problem permanently. Like everyone
else has already said good rim, bad build.

Let me put it this way I will go find someone in the area to give me
an opinion. I was wondering if the requirement of a little truing
would be necessary on a monthly basis. However, the rear was way
too much last time.

Unless you crash or sit on the wheel in transit, no maintenance should
be required. Consider that steel and aluminum do not creep and spoke
nipples cannot unscrew on a properly built wheel. So what is there to
tune up? Wheels should be maintenance free if they are well built.

Everybody thinks very highly of a person just because of a website
and I was not very suitably impressed to justify taking time off
from work for him. My time is spent elsewhere and 2 hours to go
visit is not going to appear. Thanks for the help but recommending
me to go there does little.

Build your own wheels. It isn't high tech. Actually it's more like
cooking with a good cookbook. Just follow instructions. The next
time it will be self evident an you won't be dependent on a bicycle
mechanic who refuses to read about the subject.

The same goes for most bicycle shops in this area as I had previous
visited a multitude of them. I left with impressions of
ill-informed salesmen and questionable tech support to be fraught
with long travel times.

The story that I got from the bike shop indicated that they need
periodic truing, but I didn't really buy it. So, what I really like
to know if there is a book on building wheels. I will go take a
look for such a thing.

Just to clarify a question of mine.
How out of true would the MAVIC get during normal riding? The people
that mention that they do not true their wheels, surely do not have
perfectly straight wheels?

Most quality brakes are adjusted ~1 mm from the braking surface of the
rim. Rims can easily be true to within less than .3 mm with even spoke
tension. There will be some irregularities and settling even with a very
good build. However, wheels can be built to stay true to within .5 mm
taking into account some rim irregularities and settling. You should be
able to put a .5 mm feeler gauge between the rim and a brake shoe that
is set at 1 mm and make a complete revolution with just a minimal or no
touch. As long as the rim isn't damaged or a spoke broken the wheels I
build stay within .5 mm of true. If the spokes have proper and even
tension and there is error of less than .5 mm some wheel builders won't
make any adjustments. Further reading suggestions: "the Bicycle Wheel"
