I like power supplies like this one from digikey:<br><br>Run of the mill 90-240 v AC input, 12v output rated for 50w max, ~ $22.00 CAD<br><br><a href="http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=285-1818-ND">http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=285-1818-ND</a><br>

</div>There are lots of switching power supplies in wall warts or ones the<br>
size of laptop power supplies now that are 12v. I've seen some that are<br>
4.5A at 12V which would give over the 50W you seek.<br>

</div>I'd be interested...<br>
