      True, the difference is the transfer medium. Pulsar paper (perhaps
      the standard) costs about $1.50 per 8.5 x 11 sheet. Free leavings
      from a sign shop.... priceless.

      If it works as well, something to consider, since all you need are
      pieces somewhat larger than your board design.
