I would happily pay £20 for a good quality version from a reliable

Heh, so everyone's suggesting hotwiring an old PSU. Funnily enough I
had one of those, but I binned it because it was too
big/noisy/tangle-of-cabley for easy portable use. Should've kept it and
modified it, perhaps. De-soldered the un-needed connectors, done the 7v
trick on the fan, could've been okay.

That'll learn me... :-)
