Yes, mail order they are $350. I can get one for $300, but if you
say they can be had as surplus for cheap all the better.

My real problem though is energy usage. If the things draws 2 amps
or so, it's gonna cost me a forture (when you have kids, $30 a month
IS a fortue, believe me) to run and I justcan't have thet.

Now, what if I were to concoct a motor assemble that used, instead
a DC brushless motor. Anybody have any rough ideas as to
how much less power  this was use ?
