Hi Rich,
  If you do a search on your favorite search engine for " remote
controlled power" you will find a large array or such creatures for
prices in the hundreds to thousands. For example these guys have them
for a few hundred
http://www.dataprobe.com/products/power/iboot/ibootac/index.html. If you
want anything less expensive you'll have to go to Radio Shack to find it
or possibly solder up the components yourself. I recall that the circuit
you are looking for can be found online too, just don't recall where.
