That is for a 3-day course though. The courses seem to be aimed at professional mechanics as much as home builders. If they are as comprehensive as they seem that doesn't sound unreasonable to me. They do have to make a living.
FWIW, Mr Brandt is a regular poster on rec.bicycles.tech. He can be (and usually is) a bit of a crank, but his advice is worth reading.
Definitely not a crank - I think you meant a bit cranky
More than a bit. Furthermore, he writes on that group with as much certainty and confidence on matters of which he is profoundly ignorant as on those on which he is generally regarded as expert. I suppose I'd trust his wheelbuilding book simply because enough people I do respect consider it good, but I wouldn't trust his opinion on much else without verification.
In summary, my experience of him is of an arrogant and at least partially ill-informed thug.
What Simon said (eh?).

I have built a Several of wheels from these instructions and so far none has disintegrated or exhibited suspicious tendencies.
