+12V @ 2.5A and +5V @ 1A, what is the best solution can have +/-10% on them.

I have looked at switching regs but they seem to be not the best for
availability and require expensive inductors etc for use. I want to build a
very cost sensitive device and am looking for other suggestions.

Yes heat is an issue that needs to be addresses also as a 7805 was attempted
and man does it get HOT!

Thanks.
Richard.
