If you are handy with a bit of veroboard, or able to design and etch a pcb (preferable), it wouldn't be too hard to make a little board with 7812 & 7912 regulators (i'm assuming this is what you meant by 'registers') and the required capacitors. There are plenty of example circuits on the net for using these regulators. You may want to keep in mind how many 12v modules you are planning on running. You may need to think about adding heatsinks to the regulators depending on how much current is being drawn.
Hope this helps
