How to build a $20 47A power supply

[Nard Cox]

OK, I've ordered myself a new Hyperion EOS0615i Duo3 for 170 euro / $225 shipped (not a bad price, not even compared to US prices).

So I'm looking into a PSU again and I typed this model into ebay.de and voila.
But it's more than four times as expensive and it's a USED model.
$65 incl. shipping to NL and $50 to Germany.

So if anyone has some cheaper suggestions let me know.
