Homebrew PCBs

I made a set of perfect boards yesterday with these components:

$120 HP LaserJet 4 with Verbatim toner - original may leave better finish
$10 Epson glossy photo paper
$20 Ibico 4" laminator - modified slot to allow board + paper through
Soak, paper lifts off by itself
Rub to remove excess paper particles
etch, drill with dremel drill press ($65)

Seeing as though the only consumables are board, paper, and etchant,
this is very inexpensive.

Does anyone make double sided boards this way with manual vias?
Has anyone made plated through holes at home?
