I hate to burst your bubble, but you can get good 12V power supplies 
from surplus electronics places for less than that price.  Try 
http://www.mpja.com/products.asp?dept=465&main=1;
if you need less 
current try http://www.mpja.com/products.asp?dept=475&main=1.

How much current do you need for foam cutting?

"Applied Control Theory for Embedded Systems" gives you just what it says.
