Unless you really want to build it,it would be much easier to buy one and concentrate on building the interesting bits..
Many monitors use a 12V PSU such as THIS. (£6:49 is $10.)
Don't worry about the current rating as long as it's 3A or over.  Your circuit will only take what it needs.

You can build one.

Or you could buy one.  Radio shack has one.  Many surplus stores on the internet will have them.  You might find one on some old equipment.  My old printer has a 12 volt,4.5 amp supply.

Also, just thought of this, you could build one out of an old computer power supply using one of the many instructables available.
