Amateur seismologist should build their own units, not only because it is = immensely rewarding but also because it requires understanding of the very = instrument itself. Thus your point is well taken. However, by providing our kids (future seismologist, amateur or otherwise, = scientist, and engineers) with inexpensive, effective instruments we are = providing a benefit that transcends self-gratification. I, for one, = commend John and Frank for their initiative to place these instruments in = our schools. Where perhaps, at that level, the focus shouldn't be on the = instrument so much as the result, i.e., what is the earth doing today?
