Hello Horst!

The cheapest way is to obtain 2 computer-power supplies from the
junk-yard (= for free). Then you have to open both, disconnect the
negative supply from earth-potential (but of course NOT disconnecting
the earth from chassis!!!) and connect the 12V supplies in series.

This is simple and cheap!
