"the thing is, soundboards, or real ones anyway, create the proper tone
and curve at 42% humidity.  the string tension against the board when
strings are tuned at 440cps., also is engineerd to the proper curve in
the soundboard.  therefore, all soundboards should be kept at 42%
relative humidty.  granted the DC systems are not the best way to do
this, but by far the practical way to, and are necessary and there are
no different opions on the subject because piano engineering is
mathematical and physical science.

There certainly are other options, and at around the same price.  There
are also options which will not create a gradient in the way DC's (at
least in my experience) do.
